My guess is slightly low teTature and slightly high humidity are contributing to a delayed hatch. In my experience, my bantams have been the first to hatch. What kind of incubator are you using? If it is styrofoam, AmyLynn can help you on your next batch. If it is still air (no fan), then your temps were definitely a culprit.
I don't understand what you mean by the thermometer being 94 degrees because it was new. Are you saying you were at 94 until you bought new thermometers? If that's the case, that would definitely draw out the hatch, and combined with the 55% humidity the eggs probably wouldn't have lost enough moisture for a proper air cell. This happens to a lot of people, and it happened to me. Don't let it get you down if your chicks don't make it. There are people on here that can help you be more successful next time
