I have a group of 3 weeks old chicks that I got from a breeder. I was told that two of the were BOs. The breeder also had RIR, Dominques, and black americaunas, and I got some of those as well. Previously had BCM but had sold them all. I'm curious about both of the supposedly BO chicks. One looked like a BO but is getting dark feathers on the wings. The other looks likes BO but looks to have a rose comb. Are either actually BO? If not, are they just mixes or a different breed altogether?
