two words: egg turner! makes the temperature so consistent, and also it makes for a more controlled environment. also it is easier to continue on with your everyday activities. I use the HovaBator. It has a great success rate and it was inexpensive. However I still think the best incubator is a hen
i the hen is broody i would say use her as long as she is in a warm enough space since she will be sitting there stagnenet for a long time, a broody hen is the best incubator
Go with the Broody Momma, it may take more attention from you but it will be worth it. Check on them everyday and make sure to separate her from the flock and give her own "special" ( warmer) area GL!
