Miss Lydia posted a link to this site where you have to scroll down to where it says "Leg hobbles to treat splayed leg."

I can tell you what I did twice on silkie chicks if you have vet wrap. I cut a thin strip of it about 1/2" wide. I wrapped around one leg more towards the foot. I then wrapped the other side around the other leg leaving room between the legs so they are coming straight down from their body. I covered up the vet wrap between the legs with another thin strip just to cover the stickiness. I changed that twice a day. I did it for three days. Both chickens were cured.
Please read her link as there are several methods for making hobbles and mine's only one of them.
