Hi all, we recently bought 6 new chickens, all about 5 weeks old. We've had them a couple weeks now, and I noticed the other day that this one's right eye looked a bit pink and swollen. I thought perhaps she's received a peck, her nose and left eye all look fine, and I haven't seen any dropping out of the ordinary from them. Here's a few pictures of her eye, she has been also holding it closed sometimes, as seen in the third picture. Here is a picture of her left eye that looks fine to me. I've been keeping an eye on it, and at first I thought it was looking a bit better, but tonight as I was getting them in I noticed some bubbles in her eye socket at the front. I looks like spittle. Is it possible it is only an eye injury, or do the bubbles mean it is definitely an infection of some sort? I'm pretty worried. Should I isolate her from the other chicks? (All 6 new chickens are already quarantined from our older birds.) Any ballpark figures as to how much it costs to get a swab done? Any advice?
