I'm on day 13. Candled last night and out of 6, I'm thinking there's something going on in only 2, MAYBE 3 of them. The reason I think this is because I can't see into 2 of them and the third, the yolk part looks like it's taking up most of the egg.....so I'm willing to let that one try. The other 3 when candled look basically like they did when I put them in, with the exception of the air sack being a bit bigger. It almost seems like the yolk "moves" in there when I turn the egg, it slowly rotates to the top. Can I assume that these 3 are duds are remove them? I would leave them in there, but since they are so big, they rest on each other, which is causing problems for my turner. I have them in the Brinsea mini advance. I definitely don't want to remove anything that might be trying, do these three sound like they are not developing? Thanks!!!
