Pecked (or bit by something?) is my best guess as well. I also had a chance to take her to the guy I got her from and he gave her an antibiotic shot just in case. If it looks no better by tomorrow he suggests lancing it to relieve the pressure. I think, in any case, vision is likely lost in that...
One eye is protruding and lid is swollen—the eyeball itself looks completely dark. I’m guessing an injury or perhaps a sting? I’ve been fighting yellow jackets in the area of the coop and run. She seems ok otherwise. I’ve included some pics but they aren’t very close up. Any help appreciated!
