We have a little flock of Guinea Keets and I just noticed that one of them isn't feeling well. It has a long piece of plant life sticking out of its butt and the other Keets were pecking at it and pulling on it. It doesn't seem to be able to poop the rest of it out. It's acting very lethargic and isn't moving around much. It's just standing in place with it's eyes closed. When it does walk around, it seems dizzy or disoriented. What should I do?
