I have been nursing a chicken inside my home due to frostbite for 4 weeks. She is doing great now except for the fact that she is going to lose her foot. First I thought it was a messed up egg (she hasn't laid since the frost bite), then I thought one of my kids has thrown her a bagel but them it started smelling so I took it out and opened up to see something fleshy inside. So what could it be: a) some intestinal tumor? b) part of the uterus, c) some monstrous worm? I inspected her vent and it seemed ok to me. So I am left clueless. Except for her foot issue, she has been eating and drinking fine. Today she even had a mini playful fight with me as well so she is otherwise a happy camper. For size reference it was altogether about 4 inches long and about 3/4th of an inch in diameter. It got broken into two pieces because Marcy tried to eat a bit of it. Any ideas?
