I have a beautiful hen, who has taken to the hen house and avoids the rooster. I have carried her out to free range with the others and she takes off running to the hen house. I've tried closing the door to the pen. She acts like a crazy bird, trying to get back inside. She does not appear to be sick. She has acted broody but won't sit on any eggs. She paces to and fro, during the day, and is a bully to the other hens coming to lay their eggs. I put her in a cage one day. She knocked her water over and by the time I found her, she was lethargic. I dunked her into some cool water quickly and she came back ok. Since then, I just let her do whatever she feels like doing, but would like to know, why she is doing this. She was one of my best hens..
