Overnight we lost 2 due to a rat. Now the other 2 are severely stressed out about going back in the coop. I found how it got in cause it couldn't get back out and after exacting my revenge on it I fixed the problem. Now my other 2 freak out and are going to end up hurting them selves when I put them back in. We have a large run attached to the roost. They are currently following me around the house and sit on my feet when ever I stop. I tried sitting in there with them but it made no difference. How long do you think this will last? Will they ever get over it?
