about to go into lockdown, i did my final candling and air cell markings. only 5 eggs. all 5 had movement 2 days ago. one of them had no movement tonight, but the more concerning thing is that the air cell hasn't grown at all from the marking on day 12; it was the last one i candled, and immediately upon putting on the light i said to my husband "oh this one is going to hatch last" because you can still see veins on the side of the egg. should i take it out? there is no smell.
