the eggs were set fat side down in a carton for a week? I gave a dozen eggs to a friend who's incubating for the first time. I feel so bad as my instructions were very likely not clear enough. We candled them, but most look unviable. 3 or 4 looked like they had veins. Do they have a chance?? Is it crucial that they be set pointy end down? (That's how they are now). Hoping for the best.
