I have a hen that has been brooding for 18 days on four eggs. She has two other hens in there with her as well as a rooster. Should I let them be hatched in the nest with her or take the eggs and put them in the house and let them finish in the warmer i have put together for when they hatch. I'm just afraid its not warm enough for them out in the hen house. Also dont know how the ohter chickens and rooster will act towards the new baby chicks.
