My skills with my incubators need improvement, that's no secret. If I had enough broodies around I wouldn't even try using the incubators, but I don't. Most of my broody chickens are small, so they can't cover more that 4-5 pea eggs, and my Muscovy Ducks make nests in really bad places. Those pea eggs that I stick under hens hatch in 26-27 days, and most don't need assisting. 98% won't need assisting.
So if you could convince your broodies to do what you do???
My broodies do what I can't ... they incubate at the correct temp, humidity, and turn the eggs correctly. You need to teach me how to be like a broody.
