I have a hen that I had to pull away from other chickens because of her being picked on. She was really thin and I fed her all sorts of protein to get her to eat plus layer feed to get her back from the grave. Now that she is outside, still recovering, she won't eat her feed and pacing the fence, she still hasn't grown back all her feathers and I don't want her to go back with the other hens til I know she is well and eating. She doesn't look sick, just won't eat her feed, I don't want to continue to feed her treats like eggs, meal worms, etc, I want her to eat chicken feed! I'm so frustrated and don't know what to do? If she doesn't eat, I'm sure she will die!
