I have a chicken names White Beauty. She's been sitting on her eggs since November 20th. Her eggs should be hatching in up coming days. I've made her a broody home in the garage and planning on putting heating lamp on top. We live out in New Jersey. Weather is getting to be really cold here. I don't think the baby chics will make it outside even tho I have heated lamp in there coop. I also have 4 roosters, 3 ducks and 12 other hens. Should I move her now, or after the eggs hatches ? There is another hen who also sits on the same eggs time to time, now should I remove her with them as well ? How long should the stay with their mother (s) ?
