I have a few eggs that I put under a broody hen and all was going well until today when she stepped on one and it busted. Luckily that one was infertile. But after that she has not been sitting on them. Is it still possible for them to hatch? They only have about 4 days until they hatch and it was about 80 degrees today outside but they went most of the day without her sitting on them. Anything will help!!!
