I'd have to say that so far they are just inconsistant! I was looking forward to whites, ordered them from everywhere.. have 32 now and 5 more coming, but I have changed my mind.
They don't come out consistantly, they have off colors to their down, sometimes the legs are dark instead of light. I'ts some kind of Recessive/Dominant thing with the white. White is not a color so there is apparently a lot of variation possible.
I am simply finding it frustrating to figure out what will come out of the breedings, and any that come out with the wrong color legs due to their recessive white gene, are useless for showing! I just don't know.. it's not what I expected. Breedings will yeild a lot of useless stock, and I really don't have the time or space or money to feed something that won't produce reliable offspring.
I'm selling off most all the whites I aquired already. I have 3 week olds from McMurray in the brooder, all for sale!
