No one is saying awful hatch rates are normal when coming from eggs in your own flock. But a TON of people have excellent hatches with this incubator, and with shipped eggs, you have to expect poor rates, even with great incubators.Nope. You can’t tell if an egg was fertilized after it started being incubated. If it didn’t develop in that machine it was likely because it wasn’t holding appropriate temp and it killed the embryos. I’m telling you guys. This is not how hatches are supposed to go.
