This afternoon I found my precious hen Luna by the side of the coop while the rest of my chickens were all over my yard. I thought she was dead. When I found her I noticed she has her eye swollen shut. Can someone tell me what she has? She is eating and drinking fine..I already isolated her and brought her inside. I have her in a dog crate. She only wants to sleep on the floor. I put a stick in the crate just incase. Has anyone ever seen or have had this happen to any of their chickens? Please help.
