My little bantam hen has been trying to hatch some eggs. Unfortunately for her it seems that my old rooster isn't doing his job right now because all of our eggs have been infertile. She's tried several batches and they've all candled at seven days to be empty, so today I was going to take her off of the nest. I candled the last batch, and lo! one was not empty. I think it's probably rotten though It's just too unlikely to have been successful, because in addition to everything else this particular egg was very old when I set it. I think it might smell faintly bad; but when I go near that cage all I smell is the perfume of broody poop! Does anyone know what a rotten egg looks like when it's candled? This egg would be perhaps 2 1/2 weeks along, though I don't know for sure because the hen rubbed off the setting date I had written on there. It's pretty dark inside but I can see the air cell clearly. I'm not holding out any hope, but I couldn't bring myself to take it away from the hen before consulting the forum. What do you think? When I candled it a week ago it was not dark but there was a slight shadow in there.
