Crrsted ducklings struggle is real!

[laurajones1]

I am incubating crested ducklings and I do understand the struggle! Bought 2 now fancy incubators to be able to keep up with the eggs, to rotate them is the thought. First 6, down to 2 due in 2 days now pretty sure nope. Second set of 6, 5 left due in 10 days pretty sure only 2 left. 3rd set of 11, all are good but shoot 18 days or so to go. So IS following the incubator settings the problem? 99.5°, auto turning, 60-65° humidity until last 3 days right?

Are you using an independent (calibrated) thermometer and a hygrometer? Incubator displays are often inaccurate.

Your humidity setting sounds a bit on the high side to me - are the eggs losing the proper amount of moisture and are the air cells the correct size for where they are in incubation?
