I just received a set of 14 eggs this morning and other than looking for/verifying cracks (two were cracked and weeping) is there anything else I should look for that might help me determine whether or not they're viable? I noticed that the airsac was fairly mobile on some of the older eggs... is that a bad thing? Just curious, as I get used to the whole home-incubator hatching thing. I'm pretty much stuck with getting eggs shipped to me since there's no one down here to buy them from directly. At least until I can hatch my own. These are some of my Silver Grey Dorking eggs, which are going to (hopefully) be the backbone of the hatchery, and I am just keeping my fingers crossed that I get at least a few! I have 16 Red Dorking eggs in the 'bator now, and at 7 days I can say for sure that 6 are growing. The others are iffy.
