Hi all, I've been lurking on this site for a while getting some great advice but only just joined. I've hatched two lots of chicks with my incubator successfully (tho the fox undid my hard work), anyway I have a broody so let her hatch her own. Of the six eggs, two have hatched into gorgeous chicks, three completely empty, and one seemed to be a fully formed but dead chick. I've read lots of advice on why this might happen in an incubator but nothing in why it might happen under a hen? Any thoughts? I can post a pic but didn't know if that would be appreciated... Thank you.
