Well my last hatch went great I had 100% hatch rate this set of eggs were replacement eggs from a breeder. Out of 12 eggs 9 were infertile and I kept humidity at 47 to 50% the first 18 days then had humidity at 66 to 69 the last 5 days (i let them sit for a few extra days) still air with both tabs out at 101 the entire time. the three chicks that i opened had absorbed their yolks, membrane was still moist but the chicks were dead no pip in shells. What did I do wrong? last two hatches were perfect exact same temps and humidity...
