so i believe its fertile... because shes been sitting in her nest all day on top this one egg... i have a couple questions: How long till it hatches? What should I do if she gets off the egg ( its very cold)? Will she be upset if i take her egg away and put it in an incubator? and.... If I just put the egg in a box under a big light that I used for my former baby chicks, will the egg be ok?
