Chick can’t stand anymore

[K_EP-I]

So about a week ago or 2 ago I got chicks and noticed one was injured. I thought it had an inflamed knuckle but it seems like it isn’t the case. She was getting better she was walking, eating, and drinking but today in the morning she was just laying there and not moving. After I separated her completely (i had her with another small chick) she wanted to walk but stumbled forward and just stayed laying down again. I compared a health chick and her and it see her legs are a bit wider than the others. Is there anything I can do for her? I’ve never had this happen before so I’m completely clueless.
Thank you so much
If pictures are needed I could provide some

Please post pictures and a short video if possible. Is the leg swollen? How is the bottom of the foot? Did you check for hip problems? Like a sore or anything

The leg doesn’t look swollen more like she can’t get a grip or have the strength to get up. She doesn’t have anything on her and if you look at her (to me) it looks like she should be healthy. Don’t think I can post a video

@Wyorp Rock what do you think? Neurological or muscular? Failure to thrive?

Hard to know what's going on with this little one.
Is she able to eat/drink?
What's her poop like?

Have you tried chick electrolyte or anything? Honey and water is really good for an energy boost. If its still not eating I like to give very lightly scrambled eggs. My sick birds always eat that. Sometimes ill add a little water. Just make sure its not hot!!!
