My 8 month old Rhode Island Red has been acting puny the last couple days. She is secluding herself in the run or coop, her feathers are a little puffed, and she’s not eating or drinking much on her own. She has been laying on the floor of the coop the last couple nights so we’ve helped her up onto the roost bar with the others. Yesterday I soaked her in warm water because her butt was a little dirty. She perked up a bit after drying off and (I think) laid an egg later in the day. Her poop has been watery and green (see photo). Today she was still acting tired and secluding herself so I’ve quarantined her and force fed her some sugar water and she has eaten a few bites of food and cottage cheese. She is definitely the bottom of the pecking order so I’m thinking she’s being bullied away from the food? Any other ideas? I’m not seeing any mites or worms. Breathing seems fine.
