I have an Americauna hen that is just about a year old. I came out today and saw her walking like a penguin, dragging her butt on the ground. I picked her up and below her vent is swollen. I followed some advice on the forums and gave her a warm bath, felt inside the vent for an egg, but didn't feel anything. She is leaking opaque white fluid a little bit and there was a bloody "string" that came out. I noticed about a week ago that she was really fluffed up but wasn't acting abnormally. I don't know what else to do and I'd hate to put her down if there is a chance she could get better. Any thoughts or suggestions would be greatly appreciated.
