Will eggs hatch even without a heating pad Cause i can't find a incubator and my chicken keep on breaking the eggs and eating them . I would like to have some chicks but i dont know what to do?

Eggs will not hatch if they have not been incubated either by a hen or by an incubator. And it's not the chickens that are breaking and eating your eggs. It's snakes, rats, raccoons, opossums and other such animals. I suggest you strengthen your coups defenses or bye/make an incubator otherwise you will never have your eggs hatch out.
