I remember when I first started incubating it was turn the egg once a day. Boy this was exciting because we actually got to open the incubator and turn the egg. Our chickens hatched, they were great. But as time went by we have gotten smarter and science mo betta. They said now turn twice a day.. Oh this was even more exciting. We get to open the incubator and turn the egg twice a day.. They must be out of their minds. Our chickens still hatched and they were great. But now... We must turn 5x or if we follow our automatic turners 24x. It wasn't so exciting anymore, because what was once something to look forward to is now worrisome. Our chickens still hatch and they are still great, but there must be something missing in all of this. Oh yeah common sense.
