I have Ameraucana, BCM and Olive Eggers in the incubator. I can't see into the BCM or Olive ones at all with my LED flashlight, so I only candled the Ameraucana. A couple of them have large dark masses in them, but also have veining too (can't see veining in this photo, saw it from another angle) - here's a photo (not great, I lightened it up a bit in photoshop to show the area better). It is kind of like a dark cave shape - with a U shaped area in front that is light and then dark all across the back of the egg. Does that make any sense? Is this bacteria? Something else? I didn't see any blood rings Do I hold off another few days and candle again to make a decision?
