This ain't my first rodeo. I did this last spring with a still air incubator. 2 times zero hatchlings and the last time I had 3 hatch and all three times I had 20 eggs. i was so worried trying to follow all the rules last year and had so many that just didn't pip the last time. It was frustrating. So this year I have a new circulated air bator. It is day 5 and I just shined the flashlight on them, didn't even pick them up and found at least 5 of the 10 have development. I only turned my eggs once a day last year so I'm turning them 3 times a day. Morning, mid afternoon and before bed. I just purchased an egg turner but don't want it to mess up the temp by raising the eggs closer to the heater so I can't use it since they have already been in 5 days. Anyway these are duck eggs. I couldn't get clean duck eggs out of my ducks so I gave up and dusted off as much as I could (which was practically nothing) and put them in. They look dirty. The bacteria from my hands is supposed to be awful, yet I shouldn't wash dirty eggs so It seems if your birds won't lay clean eggs, you won't succeed. And after I set those eggs they gave spotless, super clean eggs for 4 days straight. Im saving them hoping the laying goose will go broody and I will shove them under her so I can have twice the chances for live hatchlings.
