i am wondering if i should enclose my hen before my chicks hatch in like 2 days. i am wondering if she will get stressed out and kill the chicks or will she be fine cooped up for 5 days in a nesting box that is 4 ft wide and like 20 inches tall???????? will she be fine and not stressed out when i shut the door. I kind of need them on a short notice. thanks. any reply helps
