I have tried to hatch 5 different times. The first time I got not one chick out of 25. The second I got one chick out of 25. The third I got 3 chicks out of 20. The fourth I got 2 chicks out of 20. The fifth is in the bator now and due wednesday. I don't get it. I have used several thermometers, the temp is great. The humidity is great. I don't know what I am doing wrong. They were all shipped eggs and I even changed carriers thinking it was USPS. This last batch are Lisa's frizzles and NN, I am so hoping I have a good one this time. Any help would be appreciated.
