One of my one year old hens is sitting on some eggs and today was day 21. When I checked on her I heard little chirps coming from underneath her. I know there is at least one little one and I'm hoping more to come. The nest box is about 18 inches off the ground and there are 8 other hens and a rooster in the same coop. Should I move the whole box with mom and babies in it closer to the floor and/or another location all together for safety?
