I am still not completely sure, but I think that my babies are a new (ish) kind of sexlink. I'm sure I'm not the first person to do this, but I'm the first I've heard of, so it's very exciting to me. Some of the chicken experts have said that it's entirely probably because a Cream Legbar has barring in its' genes, which is one of the basis for sex linked chicks. I'm wondering if that, coupled with the autosexing characteristics of the legbar also contribute.
My chicks are all 5 weeks old now. The difference between the two that I pegged as boys and the ones I thought were girls is startling. 5 of the chicks look exactly alike. Then two of the chicks look exactly alike. The two that had the white spots on their heads that I theorized *could* be boys are very obviously boys.
Here's two of the chicks. One of the "girls" and one of the boys.
So, if this theory pans out, then I can make sex linked Olive Eggers. That would be so unbelievably cool!
