I'm fairly new to chickens. I have a two year old pair of Leghorns I acquired 4 weeks ago, then added two Rhode Island Reds and a Buff Orpington.
Originally I bought a Red, the Orp and an Aracauna. The Red immediately and repeatedly attacked the Leghorns from the moment she arrived. I almost took her back but was distracted by the Aracauna's visits to the apartments next door. So, I took the Aracauna back and got another Red because the one we had was great with my 4 yo son.
So now, both Leghorns and both Reds pick on the Orpington to the point where she is not getting anything to eat. She is flighty and runs from everyone. When I feed I put food out in two pans about 6 feet apart, then make a small pile in between the two. The moment the Orpie starts eating the others peck at her and run her off. EVERY TIME. When it rains and the others are under the coop, she is by herself under a table. They have not started picking on her constantly, but she is not happy and I am concerned.
Our coop is small, but they are only in there overnight and to lay eggs. They have a large section of my backyard to run in. It's probably a 35'x50' area with trees and bushes and lots of grass.
What can I do? I've read about isolating the Queen hen but there isn't a ring leader. They ALL pick on her. I can't lock any of them in the coop because it is far too small. I would consider getting rid of the Orpie but she is not mine. My best friend paid for her and she just stays at my house.
