Yesterday I found our favorite bantam hen standing still under the rabbit hutch - not normal. She stood on one leg. She didn't want to move, but still seemed alert. I felt around her thigh and didn't feel anything out of the ordinary (this is what baffles me, as you will see.) We took her in and since a certain member of the family insisted she was egg-bound, she spent hours soaking in the bathtub last night. This morning my sister noticed that the skin on one side of her belly had turned gray, and her left leg - the one she had been holding up - had turned an even darker gray. My sister also found that she had a nasty cut on her thigh with a thick black scab over it. I don't know what did this to her and I am even more confused as to how I missed it when I was feeling around her thigh. The hen is still alert and moving around just a little, and she will eat some. Is this gangrene? If so, is there anything we can do? I know gangrene is bad but this is our favorite hen. EDIT TO ADD: I noticed that it also feels soft, maybe a tiny bit squishy, when I press on the gray skin... not sure if this is just normal or not.
