It is day 8 of our first hatch, and we just candled them. Of the 12, we could only see clear detail in 5. Those are our Sebrights. They are all developing well and moving around in their shells. The other 7, 2 EE and 5 ME (Mystery Eggs), we couldn't see much detail due to the coloration of the shells. They are just too dark for my light to penetrate. But, we were able to determine that they are also developing. We originally had four TJ eggs, too. But we had to cull them as they didn't show any signs of development at all. So, it seems that we are going to have 12 chicks hatching on Feb 13! Seeing the chicks moving in the shell was quite amazing! I can hardly wait for the hatch!
