I put 13 speckled sussex eggs in the incubator on the 12th of July. I just camdled them and 5have of them you can see veins really well. One had a blood ring so I threw it out. The rest have an air sack at the end but I can't see anything else. Do you think those are growing or what? What would you do? I will try to get pics the next time I candle.
