We have 2 six week old silkies and 11 other breeds all ranging from 3-4 weeks. They all seem to get along. Originally one of the silkies was a kind of mommy to my fist 4 chicks. When I got more it stressed the silkie so I got her a friend and put them in a separate brooder. They kept escaping over the top to be with the others, so today I put them all together. I've been watching them and they seem fine. Should I be worried? I put my 2 tiny EEs in a brooder separate since they are still so fragile, but everyone else is pretty harty.
