Turkey poult with possible injured knee...

[Bryntee]

I bought two turkey poults at a farm store probably 2 weeks ago. I didn't notice anything wrong right away but now am seeing one of the poults is laying down a lot. I lifted him/her up and noticed one of its leg joints is larger than the other and when it stands, it goes inward. I tried bracing it but that didn't go well. Not sure what is wrong. :/ almost looks like its broken. But it walks okay just a little funny. What can I do? TIA
