I noticed that my chicken (Silver Laced Wyandotte - 1 year) had alot of crusted poop on her and upon further inspection she has a very large intestine-like looking blob coming out of her vent. It is about the size of a walnut, quite large. I washed her behind with warm water but she seems to be in pain only when I was touching or cleaning it. She otherwise was wandering the yard fine. What could it be? and what should I do about it? I would post a picture but it looks pretty gross...any help would be appreciated. Thanks
