Hi, I've been lurking on this thread and think it's really interesting to be in on the beginning of a new breed. I love the blue eggs from my hatchery EE, but a breed that is a more consistent layer of larger eggs would be great. I'm not in a position to breed myself, but am one of the backyard chicken keepers that would definitely be interested in having some U of A blue layers one day. I'm sure many others would be interested as well.
I have a question about blue egg layers in general. Have there been any studies done on the metabolic cost of producing the biliverdin pigment that colors the egg? Are there any related or potential health problems or perhaps a shorter life expectancy? Finally, and most importantly, are there any dietary considerations that would support, or maybe enhance, the blue color?
I know the focus of this thread is mainly about breeding, so I hope you don't mind my going off on a tangent.
Thanks
