Just have to wait. Usually, when one starts to 'unzip', the rest should be close behind. They hatch kind of quickly. You can see them trying to break through with their beak, leave for an hour then go back and see all these little ones trying to move around. It's quick. Have brooder kind of set. Make sure have non slip bottom like rubber type shelf liner. Very important so don't get splay legged. Also, I use 40 or 60 watt light bulb, none of those high wattage heat bulbs. Marbles in water. Don't want them to get wet and chilled or drown. I've used soda bottle cap with colored rocks. Once dried off, they move very quick! Cover brooder with soft top after week old. Good luck.
