I"m reading these threads about incubating eggs and wondering how difficult it is? Does a good incubator keep the humidity and temperature right, or do I still have to adjust things? I know some of them turn the eggs. My friend has chickens (small bantams) and has fertilized eggs, and has an incubator. She actually let me borrow it last year to incubate some eggs, but I was too busy. This year, we are getting chickens, and I want to incubate some of her eggs. So, is it a really tricky thing to do?
