PREFACE. 
 
 The work in agriculture in the high schools of the United 
 States is becoming more uniform and systematized and par- 
 ticularly is this true of Poultry Husbandry. However, the grow- 
 ing demand for a series of laboratory and field exercises in this 
 subject adapted to the needs of the high schools has been met 
 very unsatisfactorily and therefore, we offer this series of exer- 
 cises from which a selection may be made which is adapted to 
 the equipment in your school and to the particular needs of your 
 pupils. 
 
 In most high schools the equipment consists of but one of 
 each of the following: — incubator, brooder, forge, anvil, grind- 
 stone and drill press. The amount of space for bench work is 
 also limited. We have found the use of a set of exercises such 
 as these invaluable when a two-week program schedule is ar- 
 ranged so as to allow every pupil in the class an opportunity to 
 learn first handed, for example, the parts of and method of regu- 
 lation of an incubator. We have found that actual individual 
 laboratory work is vastly superior to class demonstrations, never- 
 theless, such work as the operation of an incubator or brooder 
 may be given either as a demonstration by the instructor or as an 
 exercise for the individual student. 
 
 We ofifer the following two-week schedules as suggestions for 
 ten students in a poultry course where farm shop work is con- 
 ducted in conjunction with the work in poultry : —

 The small numerals indicate whether first or second week. By 
 this arrangement each student has a definite plan of work which 
 must be performed on a definite day and no two be doing the 
 same thing at the same time. 
 
 Each of the above schedules calls for one day for finishing in- 
 completed work because many of the class cannot keep up to the 
 schedule and need more time or, because of some carelessness, 
 must repeat the exercise. 
 
 These schedules may be started on any day of the week and 
 instead of putting M sub 1, Tu sub 1, etc., we have found that the 
 actual dates of the month were better. 
 
 The schedule is very flexible and the length of time consumed 
 in making the project or performing the exercise determined the 
 number of times it was given a period or day on the schedule. 
 
 We have made free use of the publications of the United States 
 and the individual states and are particularly indebted to Cornell 
 University, Department of Poultry Husbandry, for very many 
 of the suggestions.

 LABORATORY EXERCISE No. 8. 
 Anatomy of Fowls — Internal Anatomy. 
 
 OBJECT. 
 
 To become acquainted with the essential points of internal 
 anatomy. 
 
 MATERIALS. 
 Fowls (Male), microscope, knife, large shears. 
 
 13 
 
DIRECTIONS. 
 Blood Vessels of the Neck. 
 
 (This should precede the exercise on killing). 
 
 1. Cut the neck from the body making the cut as close to the 
 body as possible. 
 
 3. Cut away the skin from the neck and also as much of the 
 flesh as is necessary to expose the blood vessels leading to the 
 head. 
 
 3. Make a drawing to show the relative position of these blood 
 vessels including the bridge or cross over the base of the skull. 
 Make this drawing as seen from the under side with the head 
 toward the bottom of the paper. 
 
 The Brain. 
 
 (This portion should precede the exercise on sticking and dry 
 picking). 
 
 1. Cut ofif the neck close to the head. 
 
 2. With a shears cut through the middle of the head and 
 lengthwise through the comb. At the back of the head you will 
 notice the brain. Find the two parts called the cerebum — in front 
 — and the cerebellum- — in the back. The cerebellum is the part 
 having white lines radiating like spokes of a wheel. The cere- 
 bellum controls the muscles. In killing for dry picking this part 
 of the brain must be pierced in order to cause the feathers to 
 loosen. 
 
 3. Make a drawing of a cross section of the head to show (a) 
 the two parts of the brain, (b) the cut which must be made with 
 a knife to stick the cerebellum. 
 
 The Spinal Cord. 
 
 ( This portion should precede the exercise on killing by dislo- 
 cation). 
 
 1. Examine the bones of the neck. 
 
 3. Are they solid. 
 
 3. Are they regular or irregular? 
 
 ■1. Draw a cross section of one. 
 
 5. Take the last two vertebrae — any two will do* — and force 
 one to slip past the other. This is dislocation of the neck. What 
 happens to the cord running through the center ? 
 
 f). What is the color of the spinal cord? 
 
 7. Why is the spinal cord so well protected? 
 
 The Breast Bone. 
 
 1. Cut the muscles away from the breast bone and expose 
 its keel. 
 
 3. Is it all bone or is some made of cartilage? Draw a side 
 view to show location of cartilage. 
 
 14 
 
3. Is the keel straight or bent? What may have been the 
 cause of this irregularity if present? 
 
 4. How can you tell an old fowl from a young one after it is 
 dressed? 
 
 5. What do a few tricky poultry dealers do to deceive the 
 public as to the age of dressed poultry? 
 
 TJic Male Reproductive Organs. 
 
 (Optional except that it should precede the exercise on capon- 
 izing). 
 
 1. With a shears cut away the breast bone but do not cut 
 away the ribs. 
 
 2. Remove the digestive organs and find two rather small, 
 dark-red, lobulated bodies lying at either side of the spine and 
 each fits into the grooves formed by the ribs. These are the 
 kidneys. 
 
 3. Turn the bird on its left side and make a cut between the 
 last two ribs. Attached to the back you will see two yellow organs 
 varying in size according to age. (At three months they are 
 about as thick as a wheat kernel and about half an inch long). 
 These are the male reproductive organs and in the operation 
 called caponizing it is these that are removed and not the kidneys. 
 
 REPORT. 
 
 1. Why is it better to cut the blood vessels after they have 
 been united by the bridge? 
 
 2. Why is it so important that the cerebellum is pierced? 
 
 3. Why is it humane to pierce the cerebrum? 
 
 4. What danger accompanies the operation of caponizing?

 LABORATORY EXERCISE No. 9. 
 Parasites. 
 
 OBJECT. 
 
 To learn to identify (a) red mites, (b) lice, (c) scaly leg 
 mites, (d) gape worms. 
 
 To learn how to treat birds to rid them of these pests. 
 MATERIALS. 
 
 Poultry house infested with mites. Poultry having body lice, 
 scaly leg mites and young chicks having gape worms. Micro- 
 scope. Carbolated vaseline. Hot water. Gape worm extractor. 
 Lice Powder. Poultry spray. 
 
 15 
 
DIRECTIONS. 
 
 (On account of the impracticability of securing all of the above 
 specimens at one time it may be necessary to perform this exer- 
 cise in part at various times when convenient). 
 
 SCALY LEG MITES. 
 
 1. Secure a fowl inflicted with scaly leg mites. 
 
 2. Draw the shank and foot to show the calcareous material 
 which is deposited under the scales and which exudes on the out- 
 side. 
 
 3. Draw the shank of a fowl with clean shanks as a contrast. 
 
 4. Lift up a scale and find a very small insect which is flat 
 and rectangular with the corners rounded ofif. Use a microscope 
 and draw this parasite. 
 
 5. Are both legs aflfected to the same degree ? 
 
 6. Can you determine where the insect begins to attack? 
 
 7. Does it appear to annoy the bird? 
 
 8. Is the scale contagious ? 
 
 TREATMENT. 
 
 1. Let the bird stand in a pail of warm water which contains 
 a 5% solution of carbolic acid. 
 
 2. Brush the legs with a small brush taking off all the loose 
 scales and dirt without causing bleeding. 
 
 3. Dry the legs and apply a coating of carbolated vaseline. 
 Ordinarily one soaking and frequent application of vaseline will 
 effect a cure. In very severe cases repeat the treatment. 
 
 REPORT. 
 
 1. Are scaly legs very detrimental to poultry ? Explain. 
 
 2. In what way does it indicate the lack of attention received 
 by the flock? 
 
 REFERENCES. 
 F. B. 530. A— 509. 
 
 BODY LICE. 
 
 1. Secure a louse and place it under a microscope and draw 
 what you see. 
 
 2. Find the breathing pores along the sides of the abdomen. 
 
 TREATMENT. 
 
 1. Dust the fowl with insect powder as described in a succeed- 
 ing exercise. This closes up the breathing pores and suffocates 
 the parasites. 
 
 16 
 
REPORT. 
 
 1. Name one or more insects which also breathed through 
 pores on the sides of the abdomen. 
 
 2. What are these pores called ? 
 
 REFERENCES. 
 Same as for scaly legs. Cir. 29 Cornell. 
 
 RED MITES. 
 
 1. Secure specimens of red mites. You will find these on the 
 under side of the roosts and not on the birds. 
 
 2. Place one under a microscope and draw. Compare with a 
 lousse. 
 
 TREATMENT. 
 • Spray with liquid lice killer as directed in a succeeding exercise. 
 
 REPORT. 
 
 1. How does this parasite affect the bird? 
 
 2. Why does it change in color? 
 
 3. Where does it live at (a) night, (b) during the day? 
 
 4. Why are cracks and crevices objectionable in perches? 
 
 REFERENCES.

 GAPEWORMS. 
 1. Procure young chicks with the gapes. Kill them and ex- 
 amine the wind pipe (trachea) and find small red parasites which 
 cover its walls and draw and describe them. 
 
 TREATMENT.

 Hens Poultry House Lice Killers 
 
 DIRECTIONS. 
 
 The House and the Appliances. 
 
 (Each student should perform this exercise at his own hen 
 house and clean out nests and roosts and spray with liquid lice 
 killer). 
 
 1. Remove all movable appliances from the hen house and 
 clean out nests and roosts and spray with liquid lice killer. Scald 
 with boiling hot water all drinking and feeding devices. 
 
 3. Clean off the dropping board and take all litter and spread 
 it out in the field or store where the hens cannot get at it again. 
 Be sure to store it far enough away from the hens so that the 
 parasites cannot find their way back again. 
 
 3. Next spray ceilings, walls and floors being careful to fill 
 all cracks and crevices. 
 
 ■i. Bring the appliances back and place them in their proper 
 positions. Spread f resli straw on the floor for litter. 
 
 THE OLDER FOWLS. 
 
 1. Catch the fowls beginning with the cocks. Drive several 
 holes in the bottom of a baking powder can and fill with lice 
 
 19 
 
powder. Hold the fowl head downward with legs well apart 
 and shake the powder into the feathers working it to the skin with 
 the free hand. Powder thoroughly around the vent. After each 
 fowl is finished place it in the house and keep it closed until all 
 are finished. 
 
 2. Repeat this operation at least twice — at intervals of five 
 
 days. 
 
 3. If there is a dust wallow, clean this out and fill with fresh 
 dust. If there is no dust wallow make one and fill with dust or 
 sifted coal ashes.

 8. What eft'ect do parasites have on chickens? 
 
 LABORATORY EXERCISE No. 13. 
 Natural Incubation. 
 
 OBJECT. 
 To learn how to set a hen and secure a successful hatch. 
 
 MATERIALS. 
 Eggs. Nest. Straw. Ground. Broody Hen. 
 DIRECTIONS. 
 
 1. Make a nest 15 inches square and 15 inches high with a 
 board G inches high in front to prevent nesting material from 
 falling out. 
 
 2. Place this nest so that the hen will not be disturbed by 
 other hens or other intruders. 
 
 3. Put about three inches of damp (not moistened) earth in 
 the bottom of this nest and on it a nesting material of chaff or 
 straw. Put this material down firmly and shape a circular nest out 
 of it. It should be slightly deeper in the center than at the edges 
 
 20 
 
to prevent the eggs from rolling out of it and thus becoming 
 chilled. 
 
 4. After you are sure that the hen has become broody place 
 from ten to fifteen eggs in the nest after dark and place the hen 
 on them. The number of eggs placed under a hen depends on 
 the size of the hen and the season. Before placing the hen on 
 the nest dust her with insect powder and in applying the powder 
 hold the hen by the feet, head downward, working the powder 
 well into the feathers, giving special attention to regions under the 
 wings and around the vent. 
 
 5. Allow the hen to come ofif at will and provide food in the 
 shape of corn, wheat and water within easy reach. A broody 
 hen likes to feel secluded and the less attention she receives from 
 now on the better the hatch. 
 
 6. In case she accidentally breaks an egg remove it and wash 
 the rest. Soiled nesting material should also be removed and 
 fresh added. 
 
 7. If a number of hens are set at the same time the eggs may 
 be tested at the end of the seventh day and the infertile eggs and 
 dead germs removed. It often happens that the eggs may now 
 be placed under fewer hens and new settings started. In this 
 way considerable time can be saved. 
 
 8. When several chicks have hatched out it may be necessary 
 to remove all but one in order to prevent the hen from smothering 
 or stepping on the chicks, or they may annoy her by getting out 
 and running away thus inducing her to leave the nest. 
 
 9. Wrap those removed in a flannel cloth and place in 
 the house in a warm place until all are hatched when they should 
 all be given to the mother who will take care of them for at least 
 24 hours without feeding. 
 
 REPORT. 
 
 1. What breeds of hens make good sitters, poor sitters? 
 
 2. When do hens turn the eggs? 
 
 3. Why was one chick left with the mother hen toward the 
 end of the hatch?

 at an even temperature. 
 
 24 
 
MATERIALS. 
 Incubator. Kerosene. Level. 
 
 DIRECTIONS. 
 
 Shears. 
 
 1. Inspect the incubator to ascertain whether all parts are in 
 correct position and in working order. Report any parts broken 
 or missing. 
 
 2. Place the incubator so that it stands level and firm. Use 
 carpenter's level testing it both from back to front and side to 
 side. 
 
 3. Fill the lamp about three-fourths full of A No. 1 kerosene. 
 Clean ofif with a cloth all oil which you may have spilled on the 
 outside of lamp. See that wick is well saturated. 
 
 4. Trim the wick square across using wick tube as a guide 
 and then turn up wick one-eighth of an inch and snip oft' both 
 corners. 
 
 5. Light but turn the blaze very low and slide the lamp into 
 enclosure as far as it will go. Lift into position. 
 
 (This operation will be governed by the style of incubator). 
 
 G. Turn up a moderate flame and if it does not burn clear and 
 true take out the lamp and fix it. Turn down flame before tak- 
 ing lamp out of enclosure. 
 
 7. Unscrew the nut on the wire connecting rod of the ther- 
 mostat so that there will be about one-half inch play between the 
 bottom of the nut and the pivot casting. 
 
 8. Do not let this nut touch the pivot until the temperature 
 reaches 103 degrees. 
 
 9. When the temperature reaches this point (103) degrees, 
 the nut on the connecting rod should be screwed down until it 
 raises the disc one-eighth of an inch or less above the opening in

 LABORATORY EXERCISE No. 17. 
 Operation of Incubator. 
 
 OBJECT. 
 
 To learn how to operate an incubator to procure a successful 
 hatch. 
 
 MATERIALS. 
 
 Incubator. Kerosene. Eggs. 
 
 DIRECTIONS. 
 
 1. Assuming that the incubator has been regulated and run a 
 day or two without containing any eggs thus warming the ma- 
 chine thoroughly, place the eggs in the tray and allow the tem- 
 perature to rise to 103 degrees. 
 
 2. Run the machine at a temperature of 103 degrees or a 
 fraction less until the eighteenth day after which it should be 
 kept at not less than 103 nor more than 105 degrees. (For ex- 
 plicit directions refer to catalog of incubator used). 
 
 CARE OF LAMP. 
 
 1. Every morning immediately after the eggs are cared for, 
 never before, fill the lamp, trim the wick as directed under 
 "Regulation of Incubator" and wipe the bowl free of all oil and 
 dirt. In trimming off charred part of the wick use a knife rather 
 than a scissors. 
 
 TURNING AND COOLING EGGS. 
 
 1. Beginning 48 hours after starting, turn the eggs twice a 
 day; once just before caring for the lamp and again about 12 
 hours later. Do this until the evening of the eighteenth day. 
 
 2. The trays must also be turned at each turning of the eggs. 
 For detailed directions see incubator catalog. 
 
 3. On days eggs are tested the eggs need not be turned. 
 
 26 
 
4. For method of turning eggs consult the catalog of incubator 
 used. 
 
 5. Varying conditions determine the length of time eggs should 
 be cooled. Consult your instructor, current bulletins and catalog 
 of your incubator for definite information. 
 
 6. Do not open the door of the incubator after the eighteenth 
 day until all eggs are hatched. At the end of the twenty-first all 
 the chicks which are worth anything will be out of the shell and 
 egg trays should be removed from the machine to give the chicks 
 more room. 
 
 7. Do not remove the chicks from the incubator until the 
 twenty-second day. 
 
 TESTING THE EGGS. 
 
 1. Test the eggs on the seventh and fourteenth days and dis- 
 card all infertile eggs and those containing dead germs. Place 
 doubtful eggs back in the incubator. 
 
 2. Get the tester ready before taking eggs from the incubator. 
 
 3. Infertile eggs will be perfectly clear. Strong living germs 
 will be recognized by the small spider-like body floating in the 
 egg. Dead germs are not so readily distinguished and lack of 
 space prevents a lengthy discussion here. Consult books and 
 bulletins for further information. 
 
 GENERAL NOTES. 
 
 1. Never jar the incubator by closing the door roughly or by 
 careless insertion of the lamp as the adjustment of the thermo- 
 stat is very delicate. 
 
 2. The door of the machine should not be open while eggs 
 are being turned. 
 
 REPORT. 
 
 1. Why should the lamp be filled after the eggs are turned 
 and not before? 
 
 2. What should be done with eggs tested out on the seventh 
 dav?

 albumin ? 
 
 9. Examine the larger end of the egg. Find the air space. 
 Draw a cross section of the egg as it appeared before you broke 
 it showing this air space. Does the air space increase or decrease 
 with age? What effect will the size of the air space have on the 
 position of the egg on being placed in water? 
 
 10. Examine the shell of an egg under a microscope. What 
 do you find? Notice the color pigment in the shell. Why are 
 some eggs darker than others even though laid by the same hen ? 
 Which eggs have the darker shells, those laid in the beginning of 
 the season or those laid later ? 
 
 11. Put some acid on the shell. What happens? What 
 causes thin shelled eggs? What kind of food should a hen have 
 to make good strong shells? Eggs with too thick or too thin 
 shells are not good for incubation. Why? What disadvantage 
 in each case ?

 Preparation of Poultry Products. 
 
 Killing and Bleeding. 
 
 OBJECT. 
 
 1. To learn how to prepare poultry for killing. 
 
 2. To learn how to kill poultry by (a) dislocation, (b) stick- 
 ing, (c) beheading. 
 
 3. To learn how to bleed poultry properly. 
 
 MATERIALS. 
 
 Fowls. Killing knife. Nails. Hatchet. Cord. Coop. Wire. 
 File. Box. Block. 
 
 36 
 
DIRECTIONS. 
 
 Preparation for killing : — ^Place the fowls to be killed in a coop 
 and starve for 24 hours, but supply all the fresh water they wish. 
 Methods of killing : 
 
 Dislocation. 
 
 1. Hold the bird's head just back of the jaw bone with the 
 right hand while the left grasps the body at the shoulders. 
 
 2. Bend the neck on (the back and twist about three-quarters 
 of the way round. 
 
 3. Jerk the head forward with a quick, forceful movement. 
 (This ruptures the spinal cord at the base of the skull and causes 
 instant death. This is the common method of killing squabs). 
 
 Sticking. 
 
 1. Take a piece of stout wire about 18 inches long and bend it 
 to form a U-shaped arrangement. This is suspended by a stout 
 cord from the ceiling so that when a bird's feet are placed in the 
 bends of the wire the bird will be at a convenient height. The 
 bends in ithe wire should be far enough apart so as to facilitate 
 picking the feathers at the base of the abdomen. 
 
 2. Take a heavy or loaded pail and place a small but sharp 
 hook in it. A long wire nail can be bent like the letter "S" and 
 one end sharpened with a file. 
 
 3. Slip the bird's feet into the loops of the U-shaped wire. 
 
 4. Double the bird's wings over the back to lessen the strug- 
 gling. 
 
 o. Grasp the bird's head with the left hand by the bony prom- 
 inence of the skull just back of the angles of the jaw, being care- 
 ful not to touch the neck and thus check the free flow of blood by 
 pressing upon the artery. 
 
 6. With the killing knife in the right hand make a cut on the 
 right side of the roof of the mouth where the bones of the skull 
 terminate. 
 
 7. Next force the knife through the groove in the roof of the 
 mouth until it touches Ithe skull midway between the eyes. Move 
 the point of the knife backward and forward to rupture the nerve 
 tissues and thus paralyze the bird and causing the feather muscles 
 to relax. (The bird gives a characteristic squak when the brain is 
 pierced). 
 
 8. Take the hook which was previously made and insert it in 
 the roof of the mouth of the bird and hang the bucket on the hook 
 to catch the blood. The hook also serves to keep the mouth open 
 so as to insure free bleeding. 
 
 9. The fowl is now ready for picking. 
 
 37 
 
Beheading. 
 
 1. Drive two nails toward one end of a chopping block or 
 heavy piece of wood so that they are about an inch apart and 
 extend about 1>4 inches above the block. 
 
 2. Grasp the bird by the legs and wings brought together in 
 the same hand. 
 
 3. Place the bird in the block so that the neck is between the 
 two nails. 
 
 •i. Draw the body away from the nails until the skull is tight 
 against them and the neck is distended. 
 
 5. Wiith a sharp hatchet sever the head from the body about 
 one inch from the base of the skull. 
 
 (). After beheading, hold the body firmly as before and allow 
 it to bleed. Do not let the bird bruise itself by struggling over 
 the ground. 
 
 7. The bird is now ready for picking. (For picking see next 
 exercise). 
 
 REPORT. 
 
 1. Why should birds be starved before killing? 
 
 2. State advantages and disadvantages of the three methods 
 of killing. 
 
 3. Why is the brain pierced? 
 
 4. What method is followed on your farm ?

 plucking by grasping them between the thumb and a pinning 
 knife. 
 
 SCALD PICKING. 
 
 1. Immerse the bird (use a bird killed in previous exercise) 
 in water which is a little below boiling point. Use sufificient water 
 for complete submersion. 
 
 2. Submerge two or three times allowing the bird to be in 
 the water about 10 seconds at a time. Do not scald the skin. 
 
 3. The feathers may now be easily removed and placed in a 
 box used for the purpose.

APPENDIX. 
 
 The following appendix is divided into 3G parts and may be 
 used for review or as work in connection with the students prepa- 
 ration for the home project. The references are very complete 
 so that some of them at least may be found in every high school 
 library. In this way a definite scheme for a thorough prepara- 
 tion for the project work is outlined. It is designed that each 
 student have a copy of this appendix and have free access to a 
 good library and after reading the data in the books as referred 
 to at the end of the questions he will sit down and write the 
 answers to them. These answers should be preserved and then 
 bound at the end of the year and form part of the report of the 
 home project.
