I keep a hatch timer from incubator warehouse by my computer screen. But when I set once or twice a week, I sometimes forget to reset it when I have a hatch complete. It is a handy little tool.I always start turning the shipped eggs day one.
Yeah that chick was early but even still I was behind on that hatch.

Maybe I should buy a second or third one.
