What in Sam Hill is this chick down??

[Trish1974]

I am test breeding a recessive white cockerel with his BBR mother. Only 4 of the 7 hatched. One classic chipmunk/wildtype pattern, 2 recessive white, and this one that seems to be a blend of both. S/he has a cape of dark gray across it's back with faint stripes similar to wildtype pattern. I know recessive white chicks can have a gray cast to them, but with a pattern showing on this one I don't know what to think. Thoughts on its color?

I dont know anything about genetics but that chick attacking its own toe really made me laugh. Thanks for posting

I'm not able to get the video to play, but I'll bet @nicalandia knows about the pattern in the down. Chickens can hide a lot of genes they carry. I suspect there's a dilute color hidden in there somewhere, but I don't know enough to even guess anything beyond that.

Seems like an Opal chick. In OEGB Opal was segregating from a line of Recessive White lines. While not genetically sequenced by the breeders working on them it is believed by them and by me that is an allelic mutation of the recessive white allele. the Wildtype is C+/C+, recessive white is c/c and Opal is c^op/c^op in this case c/c^op will look entirely white so if you crossed a white c/c^op rooster back to it's C+/c^op BBR mother you have 50% chance of hatching non-white chicks(25% C+/c and 25% C+/c^op) 25% c/c^op(White) and 25% Opal c^op/c^op this means that your hen is carrying Opal(c^op) and her son is actually c/c^op

What a beautiful bird! Thank you, @nicalandia !

The recessive white is only one of the many allelic mutations found on the Autosomal C allele. The order of dominance is C+(wildtype), c(recessive white), c^op(Opal), c^a(Autosomal albinism)

Facinating! I had no idea that opal was really just a (believed) recessive white mutation! Also, that chicken is really cute, I had no idea they came out in such a neat color.

I had no idea there were so many genes on the Autosomal C allele.

Am I the only one who thinks this bobtail chick looks similar to the chick on the video? Probably, I guess. What allele is bobtail on? Not Autosomal C, I'm guessing, though they look similar.
