Help! I noticed today my EE hen has one eye that is slightly shut. She doesn't have any sinus infection symptoms, in fact she seems perfectly fine other than her eye. It does look a little crusty though and she's not very tame so getting any closer right now was not feasible. I took this pic with my cell phone when they went it to roost tonight so it's not macro quality but hopefully enough that someone might have an idea of what is going on. I live in the San Diego area, so even though it's slightly chilly at night, nothing that can cause frostbite. Thanks for any advice!
