No this isn't a stick person..lol. (This is a duck egg, not chicken egg too) I put a circle around the size of the air sack at day 2..is it normal size or too small?? I put arrows to the very edge of a circular shadow that I see. I'm nervous it might be a blood ring? It's not prominante or redish it's just like a disc that wiggles a little. I woke up this morning to find the temp at 110* then realized I hadn't put water in when I put the duck in. I tried an egg before this one that wasn't fertile and just put this egg right in after I took the other out and forgot to check the water. That's why I'm nervous it might be a blood ring... I know it's VERY hard to see, but the second picture shows what could be a little spot that might be an embryo in the center of the "disc"??
