Been too busy lately to gather eggs every day. Ever since we added Brewster the Rooster to the coop the hens have been laying like crazy. My Lucy has been sitting on eggs for over a week. I snuck in there yesterday morning while she got up for food and marked them. She had 21. The other girls keep adding eggs to the nest but if they aren't marked I take them back out to give the original eggs a chance. My question is should I let her hatch the eggs while she is in the same coop with 14 other hens and a rooster?
