Unless you have a professional egg hatching facilities, it is likely that chickens can hatch eggs better than you can. The reason for this is that chickens work at it all the time, and never take a break. They are always checking the temperature, keeping the humidity just right, and rotate the eggs more consistently than you can.
Humility is an important lesson for every farmer. The farmer who understands they do not do as good a job as nature does will have greater and more consistent success than the farmer who blunders in their pride. There are some things that we people do better than any other species, but these things are few. Unless you can, every time, outperform natural processes at a rate that justifies the investment required, think twice about whether it isn’t better to let nature take its course.
