Every time I put eggs into the incubator, I scribble a progress sheet so I can keep track of the hatching schedule. Rather than continue drawing it new each time, I’ve decided to make and share a downloadable printout. You’re welcome to use it and share it as long as you keep the attribution intact and keep it free.
The temperature settings are particular to forced-air incubators. Make alterations on your own sheet if you’ve got a still-air incubator. Everything’s a guideline, I’m not an expert, and you ought not rely solely on this sheet as your source of information.
