Any help? Not sure if sprained or broken

[Rem477]

This is my first chicks, I had too many in there til a set up larger brooder. They liked to flap wings and run into each other. She doesn't holler when I pick her up or almost anytime but she will not walk on it. There is no cut, swelling i can see and doesn't seem deformed. She moves to back and forth but will not put on ground unless laying. What can I do? Will it just get better? I left the runt and a couple other chicks in there that didn't want to leave her. Any advice is welcome thanks. She also eats drinks and grooms like normal.

It's hard to see her legs/feet.

Can you get some more photos?

Feel of her knee joint, is the tendon slipped out of place?

The right leg, is it puffy?
