Hi Wolftracks and welcome to the thread
You've not blown it but I would advise 2 things;
Keep your temperature slightly lower at 37.2C/99F for geese, your chickens will be fine but may be slightly late.
Once the geese eggs show fertile then remove from the incubator once daily to cool them for about 15 minutes.
Here's a hatching report that should help you.
