I have a little silky that I rescued from the feed store that had spraddle leg. After a week with a hobble she's only getting worse and now her joints are swollen so I had to come up with something else to try. So this is my little invention... Its a nylon with holes cut in it with a hole for the head a hole for pooping and two for legs. I then took a broken dowel and taped to the top of the box and hung the chick in her sling from the rod. This way she can move back and forth to get her food and water and exercise those little legs. I don't know how it will work but I thought I would give it a shot.
