High Egg Production by Individual Hens, Pens and Flocks: A Complete Guide to ...

Pages 20 thru 23. Judge Card is one of my fav authors. He wrote "Breeding Laws" ( read at Hathitrust Digital Library) after 40 years in fancy poultry.
He also created the White Laced Red Cornish. One of his great gifts was making poultry breeding simple for novices to the fancy. He could often be found at poultry shows with a circle of listeners as he explained poultry breeding in simple ways.
Here is a list of the 9 questions to which the experts are replying. Helpful to print out while reading the replies.
QUESTIONNAIRE ON EGG TYPE
In order to get at the views of representative breeders and college workers on the subject of egg type, some questions were addressed to a limited number and their replies are here given. A comparison of the replies indicates that there is as yet, no common understanding between breeders and college workers as to what is meant by the term, but a careful study of this questionnaire should be interesting and helpful to all.
List of Questions
1—Do you recognize the existence of a definite "egg type" in fowls?
2—What characters do you understand to be included in the term "egg type"?
3—Can a general description of egg type be formulated that will apply with equal fairness to all breeds?
4—The Purdue Utility Score Card (see Chapter V, Part III) says body must be "nearly rectangular * * * , great depth is especially desirable * * * , the general body conformation of a heavy producer conforms very closely to a rectangle with pronounced angles rather than smooth curves." Do you recognize this as a fair standard to be applied to all fowls without regard to breed type?
5-Where no allowance is made for breed type will the strict application of above description tend to a common type in all breeds?
6-If you favor the Utility Score-Card description of egg type in general, but would adapt it to breed characters, what changes would you make in applying it to: Leghorn? Rocks? Wyandottes? Rhode Island Reds?
7—Must body capacity be relatively large in fowls of different size? That is, must the body capacity of a 200egg Rock, weighing 7 pounds, be approximately double the body capacity of a 200-egg Leghorn, weighing 3J4 pounds? If so, why?
8—Do you consider it desirable to modify standard weights in any of the popular breeds, with a view to improving egg production?
9—Is looseness of feathers (in standard Wyandottes, for example) a handicap in high egg production.'
