If he managed to get the top off the egg and can't get out the rest of the way, you can safely help him. Once that membrane has been broken by the chick, there should not be any more risk of him bleeding and he should have absorbed the yolk entirely (hopefully). Scoop him out and get him free of the shell and membrane. You will need to put him back in the bator to dry off and if you have other pipping eggs in there you will have to work very quickly and make sure the humidity stays up. You can treat his cut on his leg with a anti bacterial ointment when you get him out of his sticky situation. Good Luck.Okay the chick has managed to get the top off but I think it’s wings are stuck to the membrane and it can’t get out. I’ve tried upping the humidity but he’s still stuck. Also I think he cut one of his legs on his way out
