Rooster leg problem!

[joer77]

I have a 1 year old Ameraucana rooster that has a knot on one of he's legs. He hops around on one foot. He eats a mix of scratch feed, meat crumbles and layer pellets and roost like all the other chickens. Has anyone else had this problem. Would a round of antibiotic do any good and if so what type. He,s been this way for several months. He is my favorite rooster I have! I just want to see if I can help him before i have to put him down. thanks guys

Where is the lump located? Picture? Is it at a socket/joint area? Is it hot to the touch? Soft or hard? The first thing that comes to mind is a dislocated socket, but need more info and a picture would be helpful.
