My one year old black sex link hen has been acting out of sorts. She has a floppy comb, runny (whitish/yellow) poo down her butt feathers (haven't seen her have an actual bowel movement) and she's not interacting with the flock. She's not interested in free ranging and is just hanging near the coop. She even let me check her out (normally wouldn't let me near her) and I felt around her bottom, but didn't feel an egg or anything. I have no way of knowing if she's laid an egg recently, but she doesn't have the more classic egg bound symptoms. She walks slow, but doesn't seem to squat or waddle and she otherwise (physically) looks normal on the outside. She has such a big fluffy butt that I can't tell if it's swollen (didn't feel warmer to the touch or anything). Any ideas/experience?
