My Runner eggs came in the mail today! I bought from somebody with 100% positive feedback on ebay. I was only given 2 extras, and two were cracked. But I guess that's what extras are for. I just hope thee extras weren't cracked to begin with... I did cover the cracks with beeswax and put them in the bator anyway. I'm surprised, the box was not marked "Fragile" or anything. Anyway, when I candled them, they kind of look funny to me. I could only readily see an air sac in one of them, and there are a few with air sacs that look qutie small. Then there's a "blob-ish" area that was visible when I candled. I tried to capture it in the pictures. I'm not sure if they look normal or not. My home grown ducks' eggs have always had large, clearly visible air sacs and no weird looking things. But maybe everything's fine? Please let me know what you think! Pretty green ones! (No, they weren't shipped all on top like that. Cracked one. These next two show the "blob" in one egg. But most of the eggs looked like this. I hope you can tell where it is. It's the slightly darker area at the bottom. Thanks for looking!
