I bought six little brownish pullets from Atwoods almost two weeks ago. I had bought a dozen black sex-links from a local women (all roosters) and at that time the roos were a week old for sure but I can't be sure about the "Reds" age but they were all about the same size and no feathers development yet. Now even though the roos are bigger now the feather development is about the same. I think they are all around three weeks old now. My question: Are "Reds" from Atwoods RIR or some other breed? Is there anyway to be sure.
