Here is my puzzle. In a pen of bantams I got as a backyard flock, there are BTW Japanese (3 hens - 1 roo), 1 buff cochin roo, and 1 EE roo. The jap eggs were incubated and the first pullet has started laying - pretty clear blue eggs.
The pullet is white, with hints of tan on her body and blue in her tail feathers. And a tiny pea comb. She does not have a jap stance, and her legs are too long.
All of the original jap eggs were slightly off white.
Some of the hatchlings, both pullets and cockrels have puffy face feathers.
I sure wish some more of the pullets would start laying so I can see what color their eggs are going to be.
