So Got my eggies(khaki Campbell Ducks), The seller gave me 2 extra i was thrilled. But as i passed them over i was a ruptured air cell in 2 of them and another elongated egg cell. So im hoping for the best they are setting today, I'm going to try my best. EDIT: Day 24 and all are developing!!! [ Pics of incubator on pg 2] All active and developing fine. Just there is one with a large air cell can that cause a problem for the baby??
