Has anyone concidered that maybe the temperature in the incubator was too high? Maybe you have an inaccurate thermometer? If the eggs were hatching at 26 days, maybe the chicks hadn't developed enough to hatch properly. My runners often don't hatch untill day 30 or 32, or sometimes even later! AND it seems like the ones later in the hatching season take longer to hatch then the ones from earlier, ie. spring.
Lastly, DON'T HANDLE THE EGGS! Candle once a week (max), and sit on your hands the rest of the time. It's hard to do, especially the first time, but you live and learn, and it gets easier with each batch you hatch.
And where does Funnybunnie live? If its not TOO cold outside, I'd let momma duck hatch the eggs, and maybe let her raise 2 babies (she should be able to handle 2 and keep them warm), and take the others away. Ducks can't count anyway.
