I think my Serama is going blind

This is Hazel, she’s 5.5 years old. Her behavior has changed and I think she’s going blind. She still makes her way to food and water and treats. Pooping fine. She prefers to stay in the run and unless the treat is something bigger like a whole cucumber she just snatches at the air around it, only occasionally getting bites. Same when I have her out in the grass, she doesn’t quite get close enough to nibble the grass. She puts herself to bed on the roost about an hour before everyone else. She is a sweetheart and wants to just snuggle 🥰. I have a flock of 8 Serama’s, the oldest two will be 7 this summer :)

No real question here, just wanted to share my sweet old lady baby 😊
