My little BEI hen finally decided she was going to sit on her eggs, but she only seems to last about half a day -- at least that's how it's been for the last few days. Is there any hope of eggs hatching with such a lack of commitment on her part? It's not like it's warm out. We've been having days in the 40s and 50s. Is there a book that would have this kind of info so I can quit bugging people on the forum with questions like these?
