What do you mean by assisting beyond the basics? I've helped a shrink-wrapped chick or two, by applying warm water with a Q-tip to the edges and surface of the exposed membrane. I very carefully picked away bits of shell until I was sure there would be no bleeding, then kept the membrane moist and warm. In one extreme case, I put a heating pad in a shoebox, covered it with a towel, then added a moist soft cloth and wrapped him in it. Stuck a thermometer in with him to monitor temperature. Took a few hours, but the membrane finally released and he was free.
