This is my 1st time letting my broody hen hatch eggs, so far 2 have hatched this morning. My questions are... should I pull out the layer pellets and give her the chick food today? How soon after hatching can I clean out her cage? It's ripe due to a broody poo overnight, lol. I'd like to clean at least where she's not sitting. I never candled the eggs, so am not sure if all will hatch. Tomorrow is day 21 of her sitting on them, if there are eggs not hatching... how long do I give her/them until I know for sure they're no good? Also, can I be assured that "mom" will teach them where the food and water are? Do I need to provide a heat lamp, or will "mom" be enough for them? They are in the house.
