I have 5, just over a month old chicks, and one of them has had a runny eye. I've been keeping it clean, and putting an opthalmic antibiotic ointment on it, but now the chick is having trouble breathing. I'm thinking it's some kind of respiratory illness, but I'm new to the chicken world, and I'm not sure what to do. The chick is acting normal otherwise, eating and drinking well, and good energy. None of the other chicks are showing any symptoms, but should they be separated? Please give me any advice on how to treat this baby. Kristina.
