We have a hen that we are treating for bumblefoot. I went to check on her today and I noticed that she can't close her beak. I just changed her dressing last night and she was fine. I checked just after lunch today and her beak is like it is in the pics. In every other way (except the bumblefoot) she is normal. She tried to eat our cat's food but she couldn't. I am not sure about drinking. Any clues? Please help!!
