So i had four eggs incubating. Turns out 1 was not fertile. Two of them are still alive but one looks like it was a quitter. At first i thought this "ring" around the embryo was from concentrated bacteria so i cracked the egg open and it turned out to be a blood ring. What is this? It looks like it was still alive but this is on day 12 and should be much more mature than that so i culled it.
