HELP!!! Chick with a broken foot!!!

My baby chick has a broken foot!!! I think she got it snagged and twisted it when she got scared. The broke part is not the hock but spur. HOW DO I SPLINT THIS???

So i am new to owning chickens and i have four hens that just started laying eggs and two chicks who are around a month old. I keep the baby chickens in the same area as the big chickens but in a seperate coop.

Today I noticed that one of my chicks was limping really bad and that her foot was bent to the inside. Perfect L shape. I would like to keep her alive. I dont know how to splint her foot so that its straight and so that she can still walk on it. I seperated her and brought her inside. For now she does have a splint but it will not help her foot heal properly. It only provides enough support that she can put some weight on it. Mostly she hops around for a min and then lays down the rest of the time. can someone please help me???
