I used the link provided above and have had great results following Pete55's hatching guide: 4 goslings out of 6 eggs on my first attempt. It lists temps in Celsius....but I have a forced air and converted those temps to: 99 F until lock-down and as close to 98.6 as I could keep it during lock-down.
As to humidity, until lock-down you will be doing dry incubation with mistings and daily cool down periods after about two weeks. If you don't do this, the egg won't lose enough moisture and it will kill the goslings: I had one die fully developed in its shell due to too much fluid (I think that I had too many eggs in the bator so they didn't all lose enough moisture). If you miss a day with the misting and cool-down it will be okay, just try to do it as regularly as you can.
Anyway, good luck and be sure to post pics when you get babies!
