Yes, he's doing great now! Other than only having one functioning leg and he hops around because of it, he's a great example of the tenacity of this breed. He wasn't willing to give up so I didn't see a need to stop him from trying!
As of right now I have 1 Iowa Blue cockerel that I pulled from under a broody hen because there was clearly something very wrong at hatch, a bad slipped tendon or brake that I was unable to mend even with wrapping. He has proven to be a very tough little guy though and is now going to be moving...
