Ok so, I candled little eggbert, as its affectionatly called, this evening xD the egg is on day 6 of incubation, I know by day 7 you should see viens, but sometimes you can see somthing sooner. keep in mind, that the only other fertiel duck eggs i've candled was white pekin eggs, and that was some years ago. this is a dark tinted blue mallard egg. I see what looks like a dark mass in the middle, but i don't SEE any viens, and don't see the air sack either?? theres no way I'm opening it O_O I learned the hard way that curiosity kills the week old duckling embryo O_-..eh heh. I'm thinking of taking one of the other mallard eggs tomorrow that is in a nest and hasn't been incubated, so should be clear, like a chicken egg right??, and comparing them, but what does it sound like to y'all??
