Every time I've hatched duck eggs, they always hatch between days 25 and 26 (RIGHT when I start lockdown!), and I've hatched many different types. I always incubate at 99.2 with 3 accurate thermometers (they always read only about 0.2 apart from each other) Why does this happen? They are already 2 days old by the time they were SUPPOSED to hatch.
