So exciting. My first broody began sitting almost 2 weeks ago, and I just candled for the first time. I wasn't really sure what I was looking for...I couldn't see much in the darker colored eggs, only dark areas with the light area on the other side of the egg. Is that light area the air pockets I hear people speak of? I'm guessing that the dark area is the chick itself, and growing. I was able to see movement in a few of the lighter eggs. And to my surprise I pulled out an egg that had no dark area. I then I noticed it was also missing the orange marker X. Any thoughts?
