We got our Ammies 2 weeks after our originals. So there is quite an age difference, but all the chickens seem to get along, which is nice. They're very timid, and they like to run around. We let the big ladies go outside, then we rotate and herd the babies outside. They're a pain to get back in, i once chased one everywhere. It was probably traumatized. But theyre very sweet and beautiful birds, I recommend them. Theyre not one to flap everywhere, and theyre very very very sweet.
