My chicken’s eye has a swollen ring around it

[Jeri2911]

My black sexlink chicken is about 10 or 11 weeks old
and last night we discovered that the flesh around her eye is really swollen. Her eye is starting to shut now. She doesn’t seem to be in pain. Does anyone know what this is? Thank you!

Do you see any bubbles or foam inside the eye? That could be a sign of a respiratory disease called MG. If no bubbles, or other respiratory symptoms, there could have been a peck or sting around the eye.

I just checked and I don’t see any bubbles. And she doesn’t seem to be bothered by it too much. I’ll keep checking though
thank you!
