I bought day-old RIR chicks from our local Calico Creek store. They are now 8 weeks old. I'm not sure if they really are RIR. A few of them are all dark reddish color, but most of them are a red/brown and cream or white color. Do RIR have different variations in their color or do I have something else? Anyone know? I don't have any pictures of the older birds. I just have a picture of the chicks.
