I have been incubating my ball eggs at 90 degrees and 88% humidity... Today is day 61 and there is no sign of pipping. All the eggs still look great and started to cave in at about day 55.

I candled them the other day and I still see veins and some movement. But the babies do not appear to be taking up much room in the egg.. thought they would look more full...

Should I be concerned and cut the eggs?? Or wait til the first one pips through before cutting? what is the longest I should wait if they do not pip soon...

thanks
