Hello. This all started yesterday morning with my 6-week-old red sex link. She seemed tired and sleeping for the morning, would wake up if startled, but would get up and walk around, eat, drink, but would keep her left eye shut for the most part. She could open it, and would, but she seemed to prefer to keep it closed. Her right eye would remain open. I examined her eye and no pus or discharge, no blood or evidence that she was pecked. She stayed this way all day. Seemed fine other than her eye. This morning, two of my silkies are doing the same thing! Keeping one eye shut. Can and will open they eye, but prefer to have it closed. My buff silkie (8 weeks old) seems sleepy but my black silkie (10 weeks old) seems to be okay other than the eye. The red sex link still is preferring to keep the left eye closed. There seems to be some sneezing, if I can call it that, going on in the flock by all the chicks, not just the ones that are closing the one eye. I've Googled and Googled and haven't found anything that really fits these circumstances. Any help and advice would be greatly appreciated! Thank you!
