I have an egg that pipped this morning that has done nothing since. The chick has made a 2mm diameter circle in the egg and got rid of the shell, but has the membrane left. My humidity is sitting at 81% and I'm not sure quite what to do now? Do I leave the chick and see what happens? Or do I try and help? And if so, how? This hole was there when I got up at 7am and hasn't changed since. Am 90% sure the chick is still alive
