I wrap them in washrag folded like newborn baby wrap . If they are older I wrap them in coban with small hole cut for legs on first layer to keep it in place then I fold their legs like sitting up under them and put them in protected heat same environment and give them food and water drinks and eats at times (the incubator has constant right temp) and after bout 12 hours sometimes longer their legs will be fine. Weak at first but heading right way. I make sure I have like small handtowel or rough washcloth for them to walk on cause slick probably caused it or some have just been little weak at birth or in egg too long. I like to give them drinks of water with little sugar added gives them strength when like this.
