Yesterday my hen was fine today I went out and her eyes were swollen shut. I thought it was eye worms but I used Vetrx and no worms. Her eyes seemed better when I washed them and then put neosporin in them. They continue to swell shut unless I clean them And put ointment in. She is very chirpy and has lots of energy. I am now putting her on corid but please if anyone knows what this is or how to treat it I would be very appreciative. Also she is in a coop with three others and no others have signs.
