Remember too that blue eggshells are hard to candle IMO - Lots of time toward the very end all I can see is dark mass and an air cell. Give them the full length of time -
That is what I saw on the two when I moved them, but I thought I saw a beak or wing or something sticking up in the mass..
I may leave it a few days longer, it can not hurt anything, as I have no other eggs in or going into the hatcher.
Thanks. Makes me feel better about my bad candling..
