I have a three year old RIR hen and noticed on Saturday that she had a really poopy bottom. In the evening when I went out to shut them in the hen house, she was very lethargic and just wanted to squat, so I brought her in the house. I read what I could find about egg bound hens, and did the warm bath and mineral oil on the vent. Sunday she had another bath and part of a Tums crushed in water. She hasn't had any interest in her normal food, but she will eat bits of cheese, and yesterday I gave her some oatmeal which she ate fairly readily and then drank some water on her own. She had another bath yesterday too, and her bottom is still a poopy, curdled looking mess, and the poop I'm finding in the shavings is green. Now I'm thinking maybe she is an internal layer? If she were egg bound, would she be dead by now? And if she is an internal layer, is there anything I can do? She actually seems alert and her eyes are bright, but she definitely doesn't want to move around much.
