So I have a hen that has laid three eggs, I want to hatch these three eggs under her but she has laid a fourth egg, can I remove this egg? Or will that send her into a berserk mode and lose the other eggs? Also, what do I need to know and do for when the eggs hatch? Will they eat Layer food, or do they need oatmeal and honey or something? Do they need a heat lamp? Do I need to keep them fro the other more aggressive chickens and can I Let them outside? And one last question, how long into they can tolerate the montana cold that is coming soon?
