Looking for feedback on a pipped egg

[Jayers]

I have one egg from my six that has pipped a window- then stopped. It is an opening smaller than a dime and has been open for about 24hours. I don't plan on moving it or anything, I guess I'll find out the result in the end, but I was wondering what other's experience was.

The others have not yet pipped, it is day 21.

Do not open the bator. I was told they may come a day or two late. It could be from the temp that they didn't pip yet. How many eggs do you have? And what kind?
