My young hen tucked her head in her wing, walked in circles, and is going blind. Is it Marek?

Does she have any lice or mites?
She keeps scratching at her face and/or ears. Check inside the ears for infection.

The feathers around her eyes, can see o.k.? I'd consider trimming the fluff from around her eyes, see if that makes any difference.

You'd be surprised how many birds suddenly improve once they can see food/water.

I just trimmed the fluff around her eyes. I didn't see any lice or mites. As soon as we put her back in her cage, she started pecking at her food for maybe five or six seconds, then closed her eyes again.

I realize that this hen's problems started before she was isolated. I just wanted to make sure that she can not reach the plant with small white flowers in the background. If I recall correctly, it has a milky white sap that can be irritating to skin. Good luck with your hen.

The distance from the side of the cage to where the white flowers/ Euphorbia were hanging down is actually one foot, even though it looked a lot closer than that. I appreciate your concern.
