We have 5 barred rocks right now, they are about 3 weeks old. I just reserved 3 Ameraucana eggs, ready to hatch in 3 weeks. Our BR's will be in the coop by then, and they will be about 10 or 11 weeks old by the time our Ameraucanas are 4-5 weeks and ready to go into the coop. How do I go about all this? I'd like them to hopefully live happily together at some point, but am assuming I will have to keep them separated for a while?
