Last week I noticed ny ducks eye was squinty. At that time I didn't realize it was foamy eye but I isolated her and cleaned it with saline for a few days, put apple cider vinegar in her water and used Vet RX under her wings. Her eye looked better after a few days I put her back with the flock. Yesterday I went out and her eye was terrible foamy eye. I brought her back into isolation and started cleaning her eye again and putting terramycin ointment on it. I also put the apple cider vinegar in her water. I had some enrotex that I have given her. My worry is that she is not eating at all. There are no visibly symptoms of a respiratory problem. Is there anything else I can do for her besides the vet?
