I raised a silkie/cochin cross with my first batch of chicks that included a RIR, EE and BR. They all got along fine but the silkie/cochin is a bit of a loner. My current batch, which are 12 weeks now, consists of a black copper marans, cuckoo marans, Australorp, silver wyandotte and black silkie. I got them all as day olds, raised together. They all get along but the silkie doesn't seem to "fit in" with the other chicks. She hangs out by herself and seems a bit of an outsider. I think its a silkie thing. They are a bit "slow", and because of this, Clover is going to become our house chicken. If I was to get another "mixed batch# of chicks, I would get 2 silkies. I don't know if another breed of bantam would be as much of a black sheep as a silkie, I tend to think not.
