This is a 2 year old hen that we have and this is how I found her eye and face this morning. Excuse the lack of feathers on her back we had a couple too many roosters till they went to freezer camp and her feathers are just now growing back. I've never seen this before, none of our other chickens have this, she acts pretty normal eating and drinking. She seems to not see too well on the bad side as she runs into things sometimes. There's no nasal discharge or coughing/wheezing she doesn't act sick in any other way. She might not be eating quite as normal because her crop is rather empty but she eats when I offer a whole grain muffin as a treat. What can I do for her? Does it look infectious? Injury? Need antibiotics? Thanks for any help.
