I suggest that you acquire "Storey's Guide to Raising Ducks" by Dave Holderread. Temperature and humidity requirements can vary a great deal for various reasons. I have successfully used broody chicken hens to hatch Ancona eggs and have had a clutch fail under a broody chicken. Artificial incubation allows regular candling as long as the eggs are handled gently. I do mean gently too. Dave covers artificial incubation very well and in terms that won't confuse those new to waterfowl hatching. Having Mr. holderread's
Thanks I will have to check the library for it. I was told by other people who have successfully hatched that theirs was more in the 35% range. I just think 86 is a bit high. But maybe that's why I haven't been able to successfully hatch any.
