Baby chick leg injury

[alexthefarmlady]

I went to my farm Feed store today and I realize a baby chicken with a injured leg so I asked to see it and I didn’t think it was this bad
Any suggestions of what I should do
.
I take care of injured animals all the time and But not baby chicks so I’m kinda worried

Praying it’s a hen
