Bantam chick with weak/slightly twisted leg and potential prolapse (?)

[Anonymous Chicken]

We picked up several bantam chicks from Tractor Supply a few days ago and noticed that one of them is having trouble walking around properly. It may have gotten worse over these few days, as when we first got her she just seemed a bit more wobbly than the other chicks. Her right leg seems fine, while the lower part of the other leg is twisted slightly to the left, and she often keeps both legs in a folded position, probably because that's what's comfortable for her. Both seem a little weak, and I don't think she'd be able to put much weight on her legs if she were to stand in a normal position, though it's hard to tell. She moves around by keeping her good leg somewhat flat on the ground and pushing herself forward with her left leg's hock joint, almost walking on her 'elbows' with her bad leg slightly angled upwards. She doesn't seem to be in pain, and is able to move around as best she can. She's eating and drinking normally, as far as we can tell.
Is there any way we can help her? Is there a way we can splint her leg(s) to help her walk properly, or could it be permanent condition?

Today we had to help her with a bout of pasty and noticed that her vent seems distended. If this is prolapse (which I've heard is uncommon in small chicks), what's the best way to help a chick this small?

I will add pictures once I get the chance. Thank you in advance!

Thank you! I've read both and they were very helpful, though I am having some difficulty determining what exactly is going on with her leg. I'll post a picture shortly.

Sorry for the delay! Here are the pictures, hopefully they're clear enough to see her leg properly.

It seems like her leg has gotten worse, it seems more splayed out (so maybe it is splayed leg after all?) and she keeps getting flipped upside-down, though I don't know whether she's doing it to herself or if the other chicks are doing it. Maybe both. We might have to separate her.

I would give her riboflavin which is found in a couple of drops of Poultry Cell, human B complex tablets which can be crushed and given in a spoonful of water, PolyVisol without iron baby vitamins, and in some other chick vitamins. You can tape her toes flat with one piece on the bottom and on top for a few days. Also you can place her in a small wine glass, shot glass, or small padded cup to stand upright to strengthen her leg muscles. Keep her warm. Feed and water her often. A leg hobble made with vet wrap strips or a bandaid cut lengthwise to bring her legs within 1 1/4 inches may help if she has splay or spraddle legs. Here is a picture:
