Will you stop by this thread and tell us how it goes each time? I hope it goes as well as this! How old are these eggs when you start them? Are your next hatches all the same hen/hens? How often are you checking the bator and/or adjusting something? I check twice a day and adjust rarely. I did just put the plugs in as you mentioned to bring the humidity up but now I have to check temp every hour and I worry about ventilation.
