My mom has a broody hen that has been sitting for over 3 weeks. She was on 8 Silkie eggs but at about 12 days decided to take a break from sitting. My mom found the eggs cold. We out them in the incubator just incase there was hope. Well now the hen is still sitting after her 2 day break. If any of the eggs hatch can we give her chicks. Or is it to risky?
