I have a hen on four eggs. Two were from the fridge (only 12 hours) 1 was a nest bait egg (been in the nest for two weeks or so) and one was a funny, oblong egg. We weren't prepared for her to go broody so we gave her what we could More like a scientific experiment than a hatch. I candled them today and noticed a dark ring the went the circumference of the egg on one end. Is this the beginnings of life?? or the dark truth of a gas bubble?? any one??
