is the membrane around the hole dry? If she is stuck, you need to dampen the membrane . So warm up some water, drip a few drops into the hole, you might have to enlarge the hole just a little. Then let the membrane absorb the water and loosen itself and with some luck the chick will be able to free itself a couple hours later. Worst case scenario you have to open the shell to get it out but if the membrane is dry then try dampening it first so it can hatch by itself and if it hasn't gotten out a few hours later then open up the shell around the head, see if that is enough, don't rush things but don't let it struggle forever. It needs to hatch within the next day or it will lose too much energy.
