Our Buff keeps running away. She left the coop back in June for almost 3 weeks and came back and refused to go back in the coop. She spent the summer living under our camper and then left again last week for the whole week. She came back this past weekend screeching up a storm looking for food. I grabbed her and threw her in the coop, but now I can't let the chickens out because she'll get out and run away again! She doesn't lay anymore and now she won't eat or drink when the other chickens are around (I have to get all the other girls out of the run and then physically put her in the run alone with the food and water) She just clucks at me when I get eggs and tries to escape. Winter is coming and I can't let her live outside the coop - we have a predator problem in the winter. What do I do with her?
