Regarding yellow legs fading with production...
I have the 2001 Standard. On page 5 under the heading of "General Comments" number 9 states "Everyone should fully recognize the effect that egg production has on the body outline, head furnishings, and in the case of yellow skinned varieties, the skin and shank color of the female.
Then on page 28 under the heading "Condition" at paragraph (b) Faded Pigmentation: A fading or bleaching of color from that described int he Standard for the beak and shanks or the pigment in yellow skin breeds is a defect when the result of poor health or condition, but shall not be considered such if the natural result of heavy egg production, age, or seasonal changes.
Regarding production, on page 29 under the heading Shape and Type in paragraph (e) Body: sub-paragraph (1) it reads Abdominal Capacity: A large abdomen or large internal capacity is necessary for adequate intestinal development, which is essential for rapid digestion and assimilation of food necessary to heavy egg production. ...
So to a judge, I can only guess this means that a HEN with faded yellow on her legs and feet will mean that she will not be disqualified for the fading if he checks her anatomy and her vent to determine if she is a heavy layer. For a cock bird, faded yellow in his legs and feet would be a disqualification. If he finds her crow-headed with a tight abdoment and a dry puckered vent, yes, she will be DQ'd.
I think too, in order to push the production side of the Standard, that 4H leaders and APA/ABA Youth Directors need to inform the kids of WHY they make that physical exam and WHY it is so important. The kids think they are only checking structure. They need to know that it is actually for breeding purposes and determining whether or not a bird is a good layer.
Every person getting involved with the breeding of chickens (or anything else for that matter) needs to know the methods used to determine the likelihood of a possible good breeder.
