My first disaster was with a fancy incubator with auto turner trays that I couldn't figure out and you poured water in without lifting the top and it filled four chambers in the bottom. It was all beyond me so I gave it back and decided never to do that again!
Then I realized I had this large covered electric skillet/oven my SIL's mother left w/me when they moved to Montana. That's when I discovered a post about how this man tells this younger guy about humidity killing the birds which is exactly the problem I had the first time.
I plugged in the electric skillet oven and hatched some EE eggs into chicks

Boy did that feel good! They're fully feathered now and in one of my two warmest coops (the two smallest coops are the warmest) with a banty roo and four banty hens that think they are the parents even though those EE chicks are their same size.
I just put a towel folded in half on the bottom, set the eggs in empty plastic ice cube trays and then put a thermos top with two new wet sponges inside to give humidity for the last three days when I took the ice cube trays out and set the eggs on the towel and didn't touch them again until they started zipping and living.
I've never used thermometers or hygro/hydro?meters, measurers or all that scientific stuff I should be learning, yet. I have a fifty five gallon, twenty gallon, two fifty gallons, a seventy five gallon and a hundred gallon acrylic aquariums in the house, house plants, and pressure cook salmon and steam a like amount of rice for the dogs and chickens so its humid in the house.
I feel out of sorts at work since its so dry and static electricity zapping me, my hair standing on end and only have a twenty gallon tank there...our winters are long, cold and dry, usually so I like the feeling that its a small version of Hawaii in the home
Other people say I'm ruining the house, its too hard on the house with all the humidity but they aren't as happy or comfortable in their homes, either. I figure a home always needs repairing, its a lifelong commitment.
I'll just do the same thing this third time, hand turn twice a day and hydrate just a bit the last three days and this time, try my hardest not to help any come out of the shell- that's the hardest part for me
