Guestion. I have 11 Red Sex link chicks, and 1 buff orpington. Problem is, I can't tell them apart. I have no idea which one is the buff. So I thought I'd ask the experts, what do I look for in the two different breeds as they grow to tell them apart? I have a lady who want's the buff at 7 weeks old. I need to be able to tell the difference by then. Can somebody help me?
