Also, wanted to share:
Mr. Darcy, our white rock. He and his girl, Miss Elizabeth, passed on recently. :(
If you breed that blue copper to the black pullet, about half their babies will be blue and half black.
We purchased 6 white rocks from Tractor Supply around April. About a month later, one juvenile seemed to have respiratory issues and died. The other five remaining turned out to be all roos except for one hen, Miss Liz. We culled 3 of the roos (we are not allowed to have roosters here) and kept Mr. Darcy and Liz. Mr. Darcy got a no-crow collar or we would have had issues from neighbors. Then both seemed to have respiratory issues and just died at about four and a half months, first one, then the other. Liz had just started laying, so it was pretty disappointing. We think it was some genetic issue rather than a contagious disease because we have Rhodies and they are absolutely healthy. We are definitely not buying chicks from TS again!
They were sold as white rocks, but the sales lady admitted they were white rock hybrids with some Cornish in them. Is it possible that was the cause? I have never heard of anything like that. She insisted they were excellent layers. Naturally, I assumed that meant you could keep the as layers as well as meaties.
