I just came in and my son said my hen was dead. I went out to check on her and found her lying in the run. She can't stand on her own. I had a very busy day and didn't get to check on them after fedding this morning so I don't have a clue as to what may have caused this. Any help would be appreciated. She hatched in September and is a Black Jersey Giant. I don't have any roos. She went broody and came off the nest a couple of weeks ago. (another hen took it over) Thanks!
