Awesome. And please don't hesitate to ask, if it's something you are concerned about. No harm in getting other opinions.
I turn my hatcher on around day 17 for chick, 24 for ducks, and get the temp/hunidity stable. I run humidity 65-75%, and temps of around 101, but my hatcher is still-air. Some recommend a degree drop for the last 3 days, but I'm happy if it maintains between 99-102!
Humidity crashes (and of course heat spikes) are the worst things during the last 3 days. Make sure that humidity doesn't drop.
Check the air cells sometime on day 25. If you see no "clearish" area between the chick and the air cell, then move them to the hatcher. If there is a little clear area, then you can still move them, but you can also delay a day. Or just later in the day.
Have you read about misting duck eggs? I haven't done it yet, but will be with this set of Call duck eggs. Day 7 today!
