Hen can't stand or walk

[6girl]

When I went out to the coop this morning I found a hen laying on her side under the roost. She wasn't able to get up on her own. I picked her up and set her on her feet and she promptly face planted onto her side again. It appears her left leg is not working properly. She has no interest in food or drink and is quite lethargic. I have isolated her to my dog crate, and she did take a few steps on her own to the back corner. I suspect Marek's, any other thoughts?

I think Mareks is a good possibility, but try to rule out other things also. Could she have broken or sprained the leg? Is it paralyzed? Is there any swelling in the foot or leg joints? Are the toes curled? Have any of the chickens had any respiratory symptoms? I would place her in a crate with food and water close enough to reach, and put poultry vitamins in her water.

I couldn't find any swelling or heat or misalignment of any kind, she held the leg stiffly and seemed to be unable to curl her toes, but did better in the crate. ??? She is now sitting in a roosting position, so at least she's bending it. I have not seen any respiratory issues in any of the others.

It very well does sound like Mareks disease.

Is she using her wings to balance herself? It's a good sign if she can move it. I would try to get her to eat by tempting her with scrambled egg, and some ground meat if not salty. Be sure to add vitamins to her water, in case a vitamin deficiency would be the problem. You can temporarily use PolyVisol without iron 2 drops daily, but poultry vitamins cost less and are better for her. Here are 3 good links for reading:

Just checked on her and took her a scrambled egg, which she didn't eat - she's walking and has laid an egg, and is talking - she was quiet earlier. She's back to being wary vs. lethargic. I'm confused and have a bit of hope that it's not MD.
