would need to be done to improve the record ? How many 

 hens have you more than two years old? 



5. Suppose you have for market fifty chickens that, 

 without special fattening, will average five pounds each, 

 and will bring ten cents a pound. Now also suppose that 

 by two weeks of crate or close-yard feeding you can in- 

 crease the average weight one pound for each bird, and get 

 fifteen cents a pound for the lot. If the feed used is just 

 balanced by the increase in weight, what would be the gain 

 from fattening? 



6. Select several fertile and several infertile eggs, and 

 place them where they will keep at a temperature of eighty 

 to ninety degrees ; examine with the candler after twenty- 

 four hours; after forty-eight hours; after seventy-two 

 hours; after ninety-six hours. What do you conclude as 

 to the keeping qualities of fertile eggs, and that of infertile 

 eggs? 



7. Make a drawing of your farm poultry house, show- 

 ing all doors, windows, roosts, dropping boards, nests, etc. 

 How does the building compare with the requirements given 

 in the chapter? What needs to be done? 



8. Talk with your father and mother about allowing 

 you to take charge of a part or all of the poultry for a 

 season, sharing the income. Then study all the helps you 

 can find, and make a record for yourself and big profits 

 for both. 



9. Show proper methods of keeping poultry records. 

 Include in the items, cost of labor, feed, marketing, trade 

 marks, egg stamps, parcel-post cases, egg production, receipts 

 from spring settings of eggs, cold storage costs, and poultry 

 equipment. 



10. Show on the map of the United States the poultry 

 sections, and indicate the poultry production both in number 

 of poultry of various kinds and the egg production, as 

 shown in the last census report. 



9. Poultry Demonstrations 



1. Demonstrate how to make equipment of various 

 kinds, such as water and feeding troughs, colony house, trap 

 nests, roosts and dropping boards.
