Okay well there's this one egg I have from my White Crested duck & I have been incubating it for about 20+ days now. But the problem is I don't have a date for when it was set so now it looks like this: That's the air sack (I believe), & that dark figure inside the egg sack makes A LOT of movement. I am guessing that is the beak, maybe? But next to it is like this.. yellow thing which I also think is maybe the yolk or something. The next picture displays it a little better: My other worry is that the air sack is not...circle-ish? It is like two circles that combine with two points. Is that a problem or is it normal? The dark area that is underneath the beak looking thing is where the duck is because you can't see anything in there. So how far along do YOU think it is? My August 26th eggs are going to hatch the 22nd. So I'm not sure how far ahead this one is, so maybe some time this coming week. Thanks in advance.
