Hatching ducks.... When do I take out the turner again?

[DB_Tex]

This is my first time hatching ducklings (farm pro series bator. Meh.) I'm at day 21. I can't find the paperwork that came with the incubator! O_O
When should I take out the turner and let them sit? what side do I set as up? when do I alter the humidity? I feel silly for having to ask but better to try to get an answer than to risk the hatch perishing.

The turner needs to be taken out on day 25,Duck eggs take 28 days or longer depending on the breed.I lay the eggs on their sides on the floor of the incubator.And humidity needs to be 65-75% on lockdown...
