We have had 4 now that have died. We are not sure what the problem is. The last one I think may have been egg bound and now have another who can't roost. Her bottom looks swollen. We have bathed her in warm water and massaged the area but it doesn't seem to help. We did have a rooster who I think was the problem. He is now gone and will see how the other 3 barred rocks do. So far they seem fine. Its just the white hens that keep dying. I did see the rooster one day keeping them holed up in the roost. He would not let them out. I thought maybe he was keeping them from their feed and water. He picked on them a lot too. We tried locking him in a seperate housing but he flew out of it. Now that he is gone we want to see if he was the problem. The barred rocks seem to be very hardy and the rooster didn't seem to pick on them as much as the white hens. There are so so many things that can go wrong but we are not sure what the problem here is. Unless it was the rooster. Any ideas?
