I am at my wits end!! I have one leghorn chicken whom a neighbor abandoned and she ended up in my yard and I have taken care of her ever since. For lack of a better term she is feral, it's rare you can catch her, she completely freaks out to human touch, like nothing I've ever seen. A few days ago she started showing signs of respiratory distress, shallow breathing, sneezing, lethargic, and some funky poos (some blood at first, and now very mucousy diarrhea, with green in it). I assumed it was CRD and put her on oxytetracyline, and the feed store suggested. She has been on it a few days and I don't really see any difference. Now I'm thinking it could be coccidiosis, because of the increasingly weird droppings, but I don't know, and like I said at my wits end. Anyone have any ideas, thoughts, advice? Anything would be more then welcome. Thank you so much.
