Ok went to my chicken coop to check my hens I could not find my rooster then found him at side of road he could not move I checked him he had cuts on legs and some on face but one leg he cant stand on he can move it but cant stand on. I have locked him on own in different coop with hay on floor so it nice and soft for him I have him locked in a two days . he cant walk on the leg at all he moves using his wings. I don't know if he got hit by car or attack by land mammal but his wings are ok and no feathers missing what should I do to fix the leg? he is around 30-40 weeks old was going too use him for breeding any suggestions are welcome please thanks for reading.
