I had four duck eggs due to hatch two days ago, one came three days early, one died in the shell, the other arrived on his due date, my fourth egg is showing no sign of activity , I've candled it and it hasn't broken through the air sac and I couldn't see or hear movement inside the egg, I'm not sure whether to just leave it or pip it, I'm just concerned that its two days overdue, and I'm on edge after having problems with the other ducks, thanks in advance
