I'm trying to get one of the hens to sit. there are 11 eggs in the nest. I was marking them and one of the girls threw a fit because I was messing with them. Today, when I was removing the unmarked, all of the eggs were hot, as if a hen had been sitting on them, but every time I look outside they're all out, so no one is sitting. How long do I leave these eggs if no one starts sitting so they don't rot?
