Just wondering. Are they extra delicate? This is the first time I've incubated any shipped eggs and I received 9 nicely packaged eggs, but when I candled, all but two had detached air cells. I set them on 4/6 and I candled today and one is definetly developing with another possible one. The rest unfortunately don't seem to be doing anything. I really had high hopes for these. They're for my son's first 4H project.
