Pretty sure it's Marek's disease...

Update: He's now out and about as though nothing happened. Crowing his little heart out again, which is nice to hear since he was quiet for so long through all the leg business. Now back out with the flock, he's also back to stalking the two hens and trying to convince them to let him get closer or hanging out with the other pullets/cockerels and watching the older ladies longingly from a distance.

Thank you for the update, and glad that he is doing well. Please let us know here if there is any change. Good luck.
