I have some golden pheasant eggs due to hatch day after tomorrow. ( Yay! ) I had 2 that were obviously infertile and threw them out earlier. One of the others is looking strange and I'm thinking it died halfway through development or something, but I'm not certain. It's not nearly as solid as the others, but it is more solid than a new egg. There are shadows of something, like a triangular dark spot. I thought I saw a vessel but I couldn't be sure, whereas in the others I was completely sure. There appears to be the same kind of shape I saw in the others a few days ago going on, but its more transparent. So I'm not sure if I should toss it or wait.
