148 THE CALL OF THE HEN. 



16. If you had a flock of hens of the "beef type," how

 pelvic bones? Why? 



2. About what per cent less eggs will a hen with crooked

 Why? 



4. What is meant by "prepotency" or "amativeness" ?

 inch behind the forefinger? 



6. Which of the two would make the best breeder in

7. Some poultrymen mate females with a record of 150
