Very interesting colors can pop up sometimes, when you don't know all of the genes involved...obvious dominant & not so obvious recessive...who's the daddy's dad, mama's mom, etc. When you do not have that info, it can be a challenge at times, trying to predict feather colors of chicks.
For example, I have 4 Wyandottes, no clue who their parents were, only was told they are pure Wyandotte.
1 Silver Laced Roo
3 hens, a Blue & 2 Ivory White,
but when you see the 4 youngsters, 2 Roos & 2 hens, there is quite a bit of red feathering, especially on 3 of them.
One of the original Ivory hens does have 2 feathers with a bit of red,
that's it, just a hint of visible red,
yet look at all this red that popped up!
I didn't raise the chicks hoping for particular colors, though, so it's all good, they're so beautiful!
