I candled today (day two) and in one egg I could see a small spot with an even smaller dark spot, as though the embryo already had an eye, but it's only day two. Could it be a meat/blood spot inside the egg? It was laid by quite a young hen, so it might be possible... I'll try to get pictures so you can see what I mean. The egg was laid on Monday and has been in the quite warm pantry for a little while. Is it possible that the pantry incubated it? I've never had this happen. It's under a broody now, who is a proven excellent broody. I'm going for a little while, be back soon with pics
