I was thinking today about the levels of white that vary among pieds. It is clearly not genetic at least not totally considering the fact that a high white pied can produce low white babies. So this got me thinking and made me think about some of my many genetics and bio classes when I was in college. I remembered how some animals colors can be determined by temperature such as Siamese Cats. Also I remembered that alligators and crocodiles gender is determined by temperature while in the egg. My thought is what if variations in egg temperatures cause different levels of white in pieds. It does not seem logical for it to be completely random so if its not genetic then the only thing I can think it to be would be environment. Has anyone had multiple clutches of pied and incubated them at various temperatures to see? Has anyone noted levels of white in pieds in relation to location within the incubator?
