Darling Trudy went broody week before last! She sits on her own and adopted turkey eggs. I candled the eggs yesterday (what an awesome experience and steep learning curve!). Among a few questionable ones and one confirmed expired embryo I found a bunch that looked like this - with veins and MOVEMENT: And another one (kind of hard to photograph - in the dark with one hand...) The following egg appears to have no development, but I returned it to the nest, in case I'm wrong This egg looked suspicious. You might be able to see a faint ring of dark around the mass. According to what I had read this ring (blood ring) is an indicator of an embryo that died. After long deliberation I removed this egg and opened it up. I should have taken a photo of what I found! Amazingly, there was an embryo inside the size of a thumbnail. It was dead.
