I just "inherited" a Barred Rock hen that is the same age as my other 4 girls (3 EEs and 1 BO) - right now she is in a dog crate in the coop, so she can be seen/smelled/heard but not pecked at. How long should I leave her in? I let her out to free range last night and my other girls immed. ran over and started pecking her. How much fighting will it take to establish the "pecking order"?
