Yes, I was feeding her with a tube. I was told she was being picked on..and she was. I kept her in the house for 6 days and she got back to her old self. I just re-introduced them today and she is back in with the flock. I will have to keep an eye on that bully hen so we don't go backwards in the first hens progress.
My hen is back with her flock. Sounds like she was being bullied..but after 6 days in the house she is doing great with the other hens.. Thanks for all your comments..Its great to know I can jump on BYC and pick the minds of other chicken people.
