I have 4 adult hens and one rooster. Someone gave us four adult hens and I put them in our pen. My original chickens are being mean to the new comers and wont leave them be sometimes chasing them away from the food. Will they ever settle down and leave them alone? What can I do ? I let my chickens out in the orchard most days and it lets the new ones "rest" from being picked on, and when can I let the new ones out for awhile? It's only been a few days since Ive had them.......help!!!!
