Do hen-raised chicks need any extra provisions similar to a brooder or will their mother provide for all their needs?
Their mother will provide shelter, heat and will teach them to forage. Obviously, you need suitable quarters for the hen and if you have an existing flock, watch closely to be sure that the hen and her brood have easy access to food and water. If there is any problem, give them a separate run and house until the chicks are feathered out.
