Hi, I have an issue with a pullet that I've not seen before(I haven't seen the issue before...we've had the pullet for a couple months). When I first found her I thought she had bloody stool and figured I would treat her for coccidia. But, after getting her butt cleaned up I realized the blood was coming from her tail which had been pecked free of feathers by her coop-mates. (There are 6 pullets and they live in a mobile chicken tractor on pasture which we move every other day). She has poo running down her back side and her but/belly is free of fluff. She is not at all lethargic or sick in appearance otherwise. She is pretty mad to be quarantined. She has a horrific odor..., sort of acrid and smokey? Could this still be coccidia or what should I be treating for? Can anyone help?
