Swollen around eyes

[etammy]

Hi, I have an 8 year old hen with what looks like swollen rim around her eyes, the red skin that would be close to her eyes, seems a little saggy too. No discharge, no smell, eye ball looks fine. She is eating well. No respiratory symptoms. Any ideas. She has been healthy her whole life.

Do you see any watery eyes, nasal discharge, coughing, or sneezing? Are there any scabs around her eyes that might be fowl pox from mosquitoes? Pictures can help. She may have conjunctivitis or pink eye from a respiratory infection, or irritation from ammonia odors.
