I had separated two hens, one with a hurt leg and one that had molted really badly. I reintroduced them after a few weeks. One is doing fine, the other would not come off the roost and if she did, she got into a nest, not to lay an egg, but to get away from the other hens. Hubby and I put her out into the run this afternoon. Not only did the roo go after her, but the other hens were pecking and chasing her. I removed her to the other pen again. What can I do to help her. She acted as if she was starving when I put corn out. Help, quickly, please!
