Do I remove the Rooster from the pen when the hen starts sitting on the eggs? Also the nesting box is up 5ft in the hen house house. Do I need to bring the nesting box down or will the chicks be ok up in the hen house once they hatch. There is a ladder but I just want to know what is best. thanks! I am just worried that she won't sit on the eggs if I move the nest box down to the ground
