Hi everyone, I am on day 22 of hatching my first clutch of ducklings - mini Magpies. I've candled the eggs at day 7, 14 and 21 and it looks like out of 10 eggs, I only have one. I am worried though about exploding eggs though. I have 2 incubators running and there is a smell in one but I don't know if it is the normal humidity/cooking egg smell or if the dark egg is going bad. The shells are very light/almost transparent in these eggs and the one egg has a darkness in it that you can see, even without a flashlight. I thought the darkness was the sack of the duckling growing but now I wonder if it is a hazzard waiting to happen. Are there any good photos on the internet of what a rotton egg looks like candled? I've put the eggs on lockdown so I don't want to handle them anymore but I guess I am paranoid. Any advice on how you can tell if it's a good or bad egg?
