sorry forgot to add that I am on day 8. I need to read up on helping them hatch. Not sure I am ready to take that on. It is one thing if it dies naturally but a whole other thing if I killed it.Dark blob... ? Well, everyone loses at least a few !! what day are you on ? In my eggs I can only see a few veins if I shine the light through the top because so much mass is taken up inside of the egg. Yolk, the chick, the veins and everything between. As for the healthy egg with the odd air sac, maybe you could try hatching him/her yourself ?
