    This is happening in my duck egg:

    (The circle around the embryo)


    . . . and I learned that it's not harmful or anything . . . but it got me to thinking, and now I'm really curious:

    What causes it?

    Does anybody know?

    You can see the heartbeat by 3 days and a wiggle jiggle flippy if you watch them when you candle. You may just be getting a good view of the embryonic sac. The light usually makes them move around a lot.

    Yes, that's possible . . . :) It just really confused me, because on my egg (the picture above is not my egg) the embryo is on one side of the circle . . . almost outside of it :|, it's not in the middle. Maybe it is the same thing. [​IMG]

    Well, the embryo is going to be on the side of the yolk, yes ? Anyone who knows about this feel free to correct me - I am in uncharted territory here. But from any sketches and photo's I have seen, the embryo is next to the yolk, attached to it. So the embryo would not necessarily be in the center of the circle.

    [​IMG] I am now getting happier! I candled the egg this morning (this is day 7), and the circle is even bigger than it was yesterday. . .
