Recently bought 6 week old chicks. I noticed one began having sensitivity in her left eye as she would blink and close it often. I didn’t think anything of it at first, then I noticed her eyelids would be glued shut in the mornings with what looked like pus or something. I applied antibiotic eye drops which seemed to clear up the infection. But now she has a clear fluid filled bubble with some cloudiness on her eye. It has drained a few times but comes back. Today I removed a gel like substance from it. She has been eating and drinking although not as voraciously as the others as she weighs less than them. I haven’t noticed any coughing or difficulty breathing. No other chicken has the same eye issue and are seemingly completely healthy. Any advice would be greatly appreciated as I am very new to raising chickens.
