I have 6 peafowl at about 4 months and one (the oldest) has bloody stool. It comes to me, so I examined. The tail feathers look like it may be pulling the feathers out or cutting them off, I don't know. I fear I will lose him if I don't do something. Any ideas????? It is time to worm him again, do you think I should although he is sick?? HELP!!!
