I have a 5 week old chick that started having problems with its left eye. Started crusting over and eventually the skin grew up over it swelling to about the size of a little marble. The right eye started to water with tiny air bubbles and crusting over a little. In addition to the eye it has been having slightly labored breathing. I have been putting antibiotic in the water and neosporin on the eyes. This has been a week but tonight I was able to extract and clean out the swollen left eye it had a large M&M size ball of yellow infection. I put more neosporin on the eye area. Has anyone ever had this issue and what is the cause? I am thinking broncitis but wonder if its a insect bite being the eye was so infected. Please help me with understanding what it could be.
