114 THE CALL OF THE HEN. 
12. What is meant by “‘type’”’ in this lesson in selecting hens for 
egg-production? 
13. What is meant by “egg-type?” by “dual-purpose type?” by 
“beef type?” How do you determine each of the three types? 
14. Do we find practically the same difference in the “‘types’’ of 
male birds as in females? 
15. What difference is made in the use of food consumed by the 
“egg type’ and the ‘‘beef type?” 
16. If you had a flock of hens of the ‘‘beef type,’ how should they 
be fed as regards to quantity so as to get the largest possible egg-yield 
and prevent them from becoming too fat? 
17. Do we find all three ‘‘types” in all varieties of poultry or are 
each of these ‘‘types’’ confined to certain varieties or breeds of poultry? 
18. What does a pelvic bone 4/15 of an inch in thickness indicate? 
one */; of an inch in thickness? 
19. A hen in good condition, with a two-finger abdomen or ‘‘ca- 
pacity” and 14-inch pelvic bone, should lay about how many eggs during 
her first year. 
20. A hen in good condition, with a five-finger abdomen or ‘‘ca- 
pacity”’ and a !/j.-inch pelvic bone, should lay about how many eggs 
the first year? 
LESSON 11. 
SELECTION AND BREEDING FOR EGG-PRODUCTION. 
1. Should we breed from poultry with straight or crooked pelvic 
bones? Why? 
2. About what per cent less eggs will a hen with crooked pelvic 
bones, close together, lay than a hen of the same breeding with straight 
pelvic bones, farther apart? How can this defect be largely eliminated 
from a flock? 
3. Does a hen that has an abdomen bagging down over the rear 
of the breast bone indicate a strong or a weak ovarian or reproductive 
system? Should they be used for breeders? Why? 
4. What is meant by ‘“‘prepotency”’ or ‘‘amativeness?”’ 
5. What does it indicate, in judging males or females for ‘‘pre- 
potency”’ as described in this method, if the thumb is '/s of an inch 
ahead of the forefinger? if the thumb is 14 of an inch behind the fore- 
finger? 
6. Which of the two would make the best breeder in transmitting 
its good qualities to its offspring? 
7. Some poultrymen mate females with a record of 150 eggs each 
to males of the 150-egg type or males bred from hens with equally good 
records, and the offspring from such matings often lay only 100 or 125 
eggs on the average? In your opinion, what causes this decrease in the 
number of eggs? 
8. How many eggs should a hen lay the first year to justify you 
in keeping her the second year as a breeder or as a layer? 
9. In breeding for egg-production, would you prefer to breed from 
males that mature early and from females that lay early, or would you 
select the opposite kind? Why?
