I didn't have any band-aids and was desperate, so I got creative and used a twist-tie (like the kind from a loaf of bread, nothing fancy). Twist it gently but firmly around one leg, then draw the other leg over and twist that one. Mine have never been able to walk with it on, but I set them in a very small box, propped in/on a towel. I set the box in the brooder in a warm section but not TOO warm; don't want to fry them because they can't move. This works great if they are only a day or so old because they don't need to really eat or drink anyway. If they are a little older, set food and water where they can reach it. Usually within 12-24 hours they are good to go. Good luck!
