I know this is off topic but I posted this concern on another thread and received a very limited response. My one hen is walking around with her feathers fluffed up and clucking. She did have a wad of dried poop on her which we cleaned, she was not plugged up. She seems to be behaving ok otherwise - eating, laying, running, etc. I have not seen any indication of being infested with mites or other but I could have missed something. I’m concerned and have no idea what is going on. It’s the hen to the right.
