Hatchling Turkeys - why such a wide time range?

[ShannonR]

Nothing ended up being late in my second batch, just the two early birds. And 11 out of 12 eggs hatched. I’m wondering now if the outside temp when I collected the eggs maybe made a difference. My first big batch I started collecting when they first started laying for the year, and the temperature was swinging pretty wildly some days.

It's possible the early two were incubated in one of the incubator's hot spots, as r2elk mentioned
