Hen going blind

[ClaraK]

Hello all, I would appreciate some insight or tips to manage this.
For some background context: my hen is named Rocket and she is a 4 year old Delaware Broiler. She weighs 8 pounds.

Recently I started to notice some behavior changes. She wouldn't go to her coop at night and instead I would be finding and retrieving her from wherever she plopped down. This morning however I noticed that she was walking slow and taking careful steps. I looked her over for injuries and than I noticed her very cloudy left eye. I checked her reaction to it by seeing how close my finger could get to the eye without her blinking. She didn't blink at all. I did the same on her right eye and she did blink when I got very close.
I set her down and watched her and she would lower her head and gently bump into something, turn, and keep going. She found the food which hasn't moved and I showed her the water.
She seems to be navigating by listening to my other birds and feeling.

Any tips on managing this? She's not loosing weight, still laying eggs, and is active
