We added to our flock a week ago, a rooster and a hen. A few days ago I noticed that the hen has a nasty eye; eye is closed, swollen around the eye and if lightly squeezed liquid comes out of it. We contacted the person we bought them from, seems she gets birds from auction and has raised her own as well for years, a few of her chickens are experiencing the same thing. She is the one that said she thinks it is coryza. We separated the hen and the lady is supposed to bring us medication. We are watching the other chickens to see if anyone else has eye symptoms. I have read several threads on hear about eye disease... Coryza - the bird will always be a carrier and should be killed. Does this need done? Do I need to treat the coops or run? There are two separate coops but side by side. The hen and rooster are in a small cooper with one other hen. They are in close proximity to the other 11 hens we have. Any tips or suggestions would be great. Should I push the stuff out of her eye or leave it alone. Is there something that Tractor Supply carries and I can apply it to the affected eye?
