Chick cant extend leg!!

[Luckyhen006]

Hello everybody, so we have this chick he hatched about 2-3 days ago, and yesterday morning I realized he can't walk on one foot, he basically stands like a flamingo, and I can't even extend his leg, his other leg will extend. But this one wont! Any help is appreciated!! Thanks!

Photos of the chick and the leg?


Is the joint swollen?
Can you feel if the tendon is slipped?
