I am almost sure she has pneumonia, she is gasping for air with every breath. She is 5 months old, will not eat or drink, she is a brahma chick. She is pooping fine for now. Two days ago she broke her foot. I've been soaking her foot in Epson salts water. I don't know if that caused pneumonia. I just went and got injectible Penicillin but not sure how much to give, can someone please help me.
