Candling Help!!- Embryo Problems?? Help!!

[eggsrcool]

I was candling my eggs at day 4, and 1 or 2 out of 3 eggs could be fertile. In one that definetly was, when I turned it the embryo didn't move as well. Could this because it got stuck to the membrane? I have an automatic turner, which turns every 3 hours. does this happen often? Is it normal? Thanks

From my experience, I wouldn't make any calls until at least day 10 or 12.
