Thanks John and coldblooded.
but it's safe to cut them in this stage incubated 88.6F (day 54)? Do you removed them from the incubator once you cut them open and transfer the open egg to a moist tub or just keep them in the incubator till they come out? My prob is that if I wait them out in the incubator, I still have some eggs there that they might disturb.

thanks all.
