Last night while checking in on my chickens, I noticed my Easter Egger laying down and puffed out. My hubby picked her up and I noticed her eye lids were all swollen. There was a bump on her one eye lid, looks like a bug bite. This morning, she is walking around eating and drinking but her eye lids are both very swollen. Are chickens allergic to bug bites? In the middle of the lump I seen a little red mark. My picture isn't the best, she didn't let me near her and I tried to zoom in with my cell phone that takes bad pictures. Is there any thing I can do for her?
