One of my chicks has an issue with his leg, help!!

This baby chick was born abt 2 weeks ago and as you can see hes p behind. he had splay legs so I did the whole thing w bandaids and he was improving, but very slowly. he was one of the first to hatch but he's still the smallest. despite this he tries to run and jump, and eats and drinks like normal too. Yesterday when I got home from work, he didnt have his bandages on (not That unusual he picks at them and i replace them daily) but was just totally dragging his foot. I assume he was like that all day while I was at work bc I could tell he hadn't eaten either. I put bandages back on but now he wants to turn it all the way backwards like this instead of improved stance. he took his bandages off again and is still turning it all the way back. as far as I can tell nothings broken, my guess is he pulled or stretched a ligament. bandages dont work much anymore bc he just folds the leg inward and turns the foot around. I did notice a slight dif in positioning of his legs as shown in the second Pic. if I grab his leg I can position it like normal and can have him stand or sit w my aid and he will do it, its just that as soon as I let go it bounces back. Any tips? is it dislocated? I do know he has a scab on his left knee joint but its not a deeper injury, its older than this issue.

PS. Ik hes really small for his age, he has been growing although slow, I really wanna give him a chance bc he was doing so well.

TLDR; Baby chick had splayed stance, improved but tore bandages off and is now like this. no noticeable breaks, does not appear to be in pain. is it dislocated? how do I help him?
