I am incubating for the first time and am going crazy because out of my 14 eggs, I have only seen veins and movement in two. There are a few that have large masses in them, but I've never seen veins or movement. I'd like to place them in water to see if they are moving around in there. When can I do this? Right now I am only on day 12. I'm guessing that's too early? Thank you!
