They will find their way out, they'll start moving about the nest more and more at the bottom and little tunnels will be formed, then soon enough a little face will pop out! I did my breeding in clear bottomed tubs and had them up on a level so I could slowly slide them forward and peer up through. from about day nine they were moving more and more till out the bravest came. There will also be a whole lot of food that Coco has in there all at the bottom which they'll be nibbling on so don't you worry
