I have had chickens for almost 3 years, but I have never had a hen hatch eggs (or hatched them myself) I have a few questions: 1) My hen has two eggs in the nest that are about 8 days apart. Will she get off of the nest when the first egg hatches? Or will she sit on both of them until they both hatch? 2) Will it hurt my hen to also eat Chicken Starter? I figured it was easier to only put that food in the coop with her and the chick(s). 3) Do I need to keep a heat lamp in the coop with Mama and the chick(s)? Or will Mama's body heat be enough to keep the chick(s) warm? 4) Anything I need to keep an eye out for that a newbie hatcher might not know about? Thanks all!
