My oldest rir hen is running the other hens out of nesting boxes. She hasn't been with them for about 3 months. She's a egg eater and I built four roll away nesting boxes so I put her back with them yesterday to see if I could get her egg too. I went to check on them this morning. I had one egg but everytime one when in the boxes she would run them out. Will she ever stop this or how can I break her?
