The silkie and the buff breeders told me it would be ok since they young. I was hoping this would work. I don't have a big enough coop to separate them I guess I need to expand. They are in my bathroom right now.
How much room in the brooder do you have? Could be that they are a little cramped and bored. If you have room put in a twig or an overturned coffee can or sometime that they can climb or play on. If you can post some pics that would be great, love to see chicks!
