1. Why be influenced in your judgment by skin pigment? 



2. What is the effect of green food on the egg? 



3. Should the vent be yellow or white? large or small? 



4. How would you value the color of the beak?

6. How should the fat covering on the abdomen feel? 



7. Should the pin bones be spread or close? 



8. What should be the distance from the pin bones to the keel?

DO A LITTLE CULLING YOURSELF 



11. Compare the general forms of birds you know to be good layers 



with those that are not. 



12. Feed two hens of the same breed, one corn, the other wheat, and 



notice the effect in pigment coloring. 



13. Compare the eye rings, ear lobes and beak color of ten hens, of the 



same breed. 



14. Examine the combs of laying and non-laying hens and note the 



difference. 



15. Select two groups of fowls, one molting, one in full plumage, and 



measure the distance between pin bones and keel in each group.
