Take a normal size rubber band & put it around one leg. roll the rubber band or wind it up into a figure 8 & slip the other loop over the other leg. If the length is still to long, allowing the legs to spread to far apart, remove one side & wind it some more till it keep the legs where they should be. very much like what they did above, but rubber bands work too. Works real well in featherleg birds, but as long as the loop isn't to big it won't come off clean legged birds either
