4 day old EE chick with a slipped tendon in hock.

[niquiunique]

I first noticed it a few days ago, but it didn't seem bad, and thought it was something minor that it would recover from. It has progresivly gotten worse. After reading and examining its leg, it is deffinenty a slippen hock tendon. It is way shorted and to the side, and swolen. I trided poping it back but it is too tight, i wish I had caught it sooner

Any advise/links of fixing this problem would be appreciated.
