I have had a 10 day old embryo in my incubator with pretty stable temperatures and humidity for a while now. What has me questioning it's mortality is that it is not moving like it used to on day 7. Everything just seems loose in the egg. When I candle it every time I move the egg, the embryo and air sack moves as well. I personally can't see any well defined veins anymore but I also don't see the dark line that indicates its death either. It doesn't smell or seem like it's rotting, but it has gained a few specks on its shell. Is my embryo dead or am I candling him wrong? I use my phone's flashlight to see and candle him.
