My silkie hatched I think four chicks today. I'm getting conflicting advice. Our local farm store says to take the chicks inside with heat lamp and leave mom hen outside or the babies will die. I've also heard to just let the mother take care of them. I live in Maine and our nights are getting down in the twenties. She is in the coop inside a box and Ican start putting the heat lamp on at night but not sure if that will be enough. Any advice out there?
