Hi there, I have some sort of an emergency with my hen. We've had her for almost 2 years, but about 2 days ago I noticed her left eye was swollen, which it wasn't the day before, I thought it was just going to go down in a couple of days, but it doesn't seem to be going down and the eye socket seems to be getting watery. I think it's a spider bite, but what else could it be?
