please help me help this little chick. she (and 5 others) just came home yesterday. all seemed fine until this morning, i noticed some blood on her bum. while wiping it off with a wet papertowel, i noticed that her rectum is protruding outside of her body. it's roundish, about the size of a small pea. she's acting fine i think...just like the rest of them, though she is preening the area. i believe that she is eating and drinking. i am going to isolate her so that i can see for sure if she's eating and if she's pooping. has anyone ever dealt with this? how should i care for the area? thanks in advance for any advice!!!
