My hen has hatched 13 eggs over a period of 2 weeks. I do have a concern about the 2 week old chicks vs the 1 day old chick. Is it normal for the hen to still sit in the nest all the time? The chicks are out running around while she stays sitting. Surely she doesn't want more eggs to sit on. Also, how long will she actually protect her chicks before she turns them loose on their own? It's kinda funny to see her with all her different size chicks trying to keep them all together.
