I have a place for them. That's where I wanted them to hatch. Even if they don't walk away for a few days, the other hens get into the nest as soon as she gets off. I worry about the other hens the most.The chicks will stay under the mother for a couple of days They don't walk instantly. If you are really afraid they will fall out to the nest, tack a cardboard cover over the face of the nest just after the hatch. Prepare a place the hen can raise her babies alone for a while.
