Minxfox,,the egg moving is a good sign,,shows activity inside the egg.If you hold the egg close to your ear you can hear "pecking" and as the chick gets stronger,closer to pipping,you can hear it make "cheeping" noises as well.Once it "pips" check the time,,I have seen them take 48 hours from that time to make it out,but everyone of the peachicks that takes that long to emerge I always have crooked toes,or spraddle legs.If they are strong and other peachicks are hatched out already and continue the peachirpping back and forth,this seems to encourage the others to get out faster. But if you only have one due to hatch,it may take longer.
I always notice the time when it pips,,and if 24 hours passes by and no progress,then I begin to peel shell back. If I notice any blood coming from the membrane I immediatly stop,and wait another 4 hours to possibly peel,or crack some more shell off.Sometimes you will notice the inner membrane has stuck and dried on the peachicks head,or wing and this may slow down it's pipping progress,,kinda looks like a mummy inside the shell.Of the membrane has dried and no blood is coming from the membrane being torn away,and it has been longer than 24 hours,,then I wouldn't hesitate to help break the shell,possibly 1/3 of the way around,then wait for an hour and see if the peachick makes progress on it's own,,and if not,peel some more shell away,,,until it's very possible you have helped the chick out entirely.Sometimes they are just too weak from an overly hard shell,or from the membrane drying on them to get out on their own,and they are worth too much not to intervene in my opinion.
