Hello. I have a batch of cornish X broiler chicks that are 2 1/2 weeks old. I noticed the last couple of days that one has what I think is slipped tendon. One hock is definitely swollen and it puts little to no weight on that leg when it walks around. It is still able to get to the food and water. Should I cull it now to put it out of its misery or wait to see if it can get to cornish game hen size? Thanks for your help.
