I have a Maran about 10 weeks old and 2 Silkies about 9 weeks old. I just got 3 (a Leghorn, a Wydonette, and a Red Star) about 12 weeks old and much bigger than the original 3. How long will they peck at each other? The new ones seem to ignore the silkies, they peck at the maran (she was the top chicken for the last week). I left the new ones in a crate in the coop for a while and then let them out supervised, they grazed and ate...pecking at the others for about 45 minutes....I decided to re-crate the new ones. I am afraid my Maran will be pecked to death...there is alot of squaking and posturing and the pecking. Now what?????
