I have a 24 week old cuckoo maran that I expected to see dead this morning but she is still alive. She is lethargic, just sitting and deep breathing but no rattles, mucous, etc. She ate some hard boiled egg, some baby bird food/vitamins. I also gave her several drops of bird vitamins. While doing so, she let out a watery poo but it had no blood in it. My question is should I treat for cocci? I have corrid & sulmet on hand. None of the other birds are exhibiting any signs of illness.
