I don't know if my chicken is egg bound or what is wrong. She was fine yesterday but would not get off the roost today. When I lifted her off the roost, she could not walk. She has a smushy underside that is bulging. Any help would be appreciated. Edited to say when we rub her stomach towards her runt, some whitish/yellowish poop comes out. She also has some stuck to her feathers below the runt area. Update: She has expelled some yellow stuff from her vent and pooped (liquid brown) some but still is not eating or drinking. I've got a heating pad under a towel that she is laying on but she is very very weak at this point.
