My 3 month old Barred rock rooster has a leg problem. He has been isolated from the rest of the crop.His right leg kind of hangs out in front .he can't move it at all. There is no swelling or any visible injuries.it looks just like the other foot, except his toes are in a loosly clinched fist. Today is day 6 without improvement.He is eating, drinking, and pooping normal, and it doesn't appear to be dislocated. Any advise would be greatly appreciated. Troy in Washington.
