Came home today to find my rooster not able to put weight on one of his legs - he was in the barn (normally the coop) and didn't move when I approached (not normal). He's full grown, is a very active rooster and he watches over his flock. I don't know what to check to see if he's got a break or ? I can't see any damage to it nor are there any injury looking places on him. Can I splint the leg? Or take him to the vet? He's currently in the coop with food and water. Thanks for any advice.
