I candled 44 chicken eggs tonight before I put them in the 1588 for hatching in the morning. Out of the 44, 43 had viable embryos. I had one small white egg from a polish that was clear. I am amazed. I have NEVER had this kind of result. I better build more brooders. I need to edit this. I remember now that I had 40/44 eggs good. I had moved three bullet shaped eggs to the back as I was candling and added them to the total by mistake. Still, that's 90% of the eggs that developed.
