We bought a house and the lady left three of her hens and a rooster behind so we decided to keep them. Well they free range and have been all their life but that’s all we really know about them. We would go out to the coop early in the morning open it and they would go free range wherever they wanted, there is no fence. And at night they would come back and we would lock them back in. Well now they don’t even want to leave the coop. Our dogs did chase them at first and we would run after them to put them in the house so the chickens could have peace, could it be that they are scared to come out now?
