I just had the same issue, but I still did dry hatch but NOT under 30% humid and had a wonderful hatch rate considering all were shipped!! even at last candle the cells were different but the smaller air cells actually took a day or two longer thats all! fingers crossed for you!!Also, I have a question with humidity. I had eggs shipped to me in which some were set when they were 12 days old and I also set eggs that were only 1 - 2 days old from the nieghbor. The shipped eggs have huge air sacs because they are older and probably delt with low humidity conditions during shipping. My neighbor's eggs air sacs are smaller since they were in the incuabtor almost right away. Does anyone have an idea for compromise between the 2 for correct humidity levels?
