Can she walk at all? Do the toes curl?
I put a cast on my chick with curled toes, but she needed incentive to come out from the heat plate (in other words, we'd go in every couple of hours and remove it). This ended up being the right call. It forced her to put pressure on the legs for strengthening.
I couldn't get vet wrap to work for me, but there's a blue medical tape you can find at the drugstore that's marketed for sensitive skin. Worked wonderfully, especially after I made some cutouts between the toes (be very careful while doing this, obviously).
