I decided to abandon the body wrap. The chicks looked miserable and were on their sides when I went to check. On the advice of someone in another thread, I put them in cups. These little 1 cup pyrex bowls seem to do the trick. One chick is already able to stand up (if shakily) and is trying to jump out. I lined them with paper towels for traction and absorption. I'll just run them through the dish washer on sanitize.
