Humidity for hatching duckies?

[ashswag14]

I know I've asked this before in the duck section but I still haven't figured it out. Some sites say 35% and some say 86% :/
Its a still air if that changes anything. this is my first time hatching anything besides chickens.

I had the same problem when I hatched duck eggs, I got quite a few different figures, so I decided to hatch them at the same humidity as chicken eggs. 40-45% and then 65-70% for lockdown. It worked out fine, I had a 100% hatch rate.

Ok I'll try that. Thanks!
