Its a splayed leg. If you didn't treat it right away, then it probably won't survive. You could try putting a bandade between the legs right above the ankles with the pad of the bandade as the width between the legs and wrap the ends around the legs. Its probably too late, but try it if you want to. I also sometimes put something non-slippery inn a mug, and put the chick in that as well. The sides of the mug keep the foot from going out too far. I take it out several times a day so it can eat & drink. If after 2 days it still isnt right, then it won't get better.
