Well I just candled the eggs in the bator. Yeah I know its only been 2 days, but I wasn't looking for veins or anything. I was checking for exploders. I put eggs in that were a little old and I was doing a preliminary sweep to check for bad eggs. I'm glad I did becasue there were a dozen duck eggs that had dark spots. They should not have dark spots after only a couple of days. I pulled those and rearranged the others. I'm trying to make room in the bator as soon as possible to get more eggs in. I am going to work on a staggered hatch and keep going until I run out of eggs or cold weather sets in. By cold weather, I mean more snow in the forecast. That should (BETTER) be a long ways away. As soon as I get enough eggs to fill a rack, I'm gonna throw some quail eggs in.
