solsken are the ones hatching now the ones from Buddy? If so what kind are you hatching. I have five of his BCS due. If you are hatching wheatons from him dont be surprised if it takes 22 to 23 days to hatch. Seems their eggs are harder and they have a harder time pipping and zipping. I had to hand deliver all my wheatons they could start pip but then couldnt get any farther. But these were the fertility test eggs for Buddy so they were early eggs. Yours was after we knew fertility. I do Buddys fertility test. The BCS due in the next few days were the fertility for his BCS, The BCs seem to hatch easily; If you are using the egg carton method might not want to 8 of the wheatons pipped in the bottom part of egg and smothered against the cardboard of the carton the rest I had to take hours each getting them out of their shells one stage at a time; It was worth the time but was so thankful god was with me and I knew how to do it or would have lost them all
