I currently have 12 chickens--9 standard and 3 bantams. They were all hatched and raised together from day one, and they do just fine together. I'd like to add some more (maybe 5 or 6) chickens this spring (will raise from day old chicks again) and plan on getting all standard breeds this time--possibly wyandottes, bcm's, australorps, sussex, or brahmas. I'm curious how the new chickens will do with my silkies, though. Obviously, I'm going to have to wait until the new ones are big enough to introduce them to the rest of the flock, but I'm worried by then that they might be big enough to effectively pick on my silkies. Or will my other chickens step in and prevent that from happening? My silkies have NEVER been picked on by my other birds--actually, I've watched them come up from behind and peck a big chicken in the butt to send it scurrying. Have any of you ever done this? How did it go?
