I just used the thermometer that came with the incubator and it read 99 the whole time. I never cross checked it with another. They seem healthy and active and are eating and drinking. This is fun!
My friend gave me a dozen Bantam eggs so I dug my Incubator out I've had for ten years and never used and put them in. Now 18 days later I have 6 chicks so far. Isn't that kinda early for them to hatch?
