I set some eggs 11 days ago, then realized that the temps were too low for the first four days. I raised the temp and waited a few more days before candling. I've candled all of them and two are crystal clear, like nothing going on in them at all. The other nine are dark. Really dark inside. I don't see any veins, they're just dark. There is only one that seems remotely hopeful and even that one is questionable. I've decided to set another 10 eggs now, and do a staggered hatch (if the first batch hatches at all!) rather than wait for these eggs, and just be disappointed. I'm bummed. I think they're all going to be duds. I'm just confused as to why two are so clear, yet the rest are so dark?
