Lynzi, that's nuts that your ducks are so early! Was the temp running high? My ducks are in trouble and are going to get grounded to the run because they keep going away farther than I am comfortable with. I'm putting nine eggs in the incubator today since I've had lots of interest in ducklings.
I have no idea, according to my Brisnea it's been at a steady 99.5-99.6 degrees. Is that too high for ducks?? I have another temp inside the Brinsea that stays in between the 99-100 spot. So it seems to have been steady.
