I have a chick that pipped in the middle of the night. Around 5:30am there was about a dime size hole. At 8:30am the hole was huge, almost half way around the egg. The shell is broken off in that part and you can see the membrane (white). Part of the chicks wing is out of the shell and dried off now. Should I intervene? It was peeping occasionally, but have not heard it in a while. It is now nearly 4pm, nearly 12 hours since it began. I have seen movement though not as much as before. Never done this before and don't want to lose this chick when it is so close. Please help.
