*Update*
So, a while ago, I candled my broodies eggs. They were on day 12 and I saw absolutely nothing in most of them. There was a green egg that I could barely see into at all, so I left it. Although, just in case, I gave her five more eggs. Today would be day 7 for them. I candled them, and saw something but a jumbled yolk. I also tried candling the green egg again. Usually I can see a little past the air cell, but this time I couldn't. I'm hoping that's a good sign. It goes into lockdown on Saturday. If it doesn't hatch, I think I'll just have to get some day old chicks for her.
