Well, we did it in 1973 with duck eggs. Someone gave my mother an electric skillet and she didn't like it, so she gave it to me and my wife. We were unsure how to use it; everything seemed to stick to it. That was before teflon. So we decided to hatch out some ducks with it.
Duck eggs take four weeks, and we didn't plan well. We had a wedding to go to back east in that last week. So my father in law took the skillet and eggs to his barber shop and set it up for that week. He rotated the eggs and spritzed them to keep them damp. They were wrapped up in barber shop towels which he changed regularly.
They hatched out the day after we got home.
Sadly, one of the ducklings fell out of the skillet and then crawled under it. When the darn thing kicked on again, it killed it.
My mother used to talk about how they used to hatch out eggs in a manure pile. I guess it worked. Also, my father talked about a well endowed French lady that hatched eggs in her bra.
So, I guess there are a lot of ways to incubate eggs. We didn't know what was involved in the process. That shows the constructive value of ignorance.
Give it a try; what have you got to lose but a few eggs. Just be sure and turn them and keep the humidity up. You might want to run the thing for a day or two prior to putting the eggs in. Try and get the temperature steady at about 101 degrees or so.
Good luck,
