This all makes total sense to me. And I should say at the start that I have zero experience of broody hens. What I don't understand is why on BYC there are so many horror stories about hens wasting away sitting on nests for what sounds like weeks even when there aren't any eggs.
In nature if a bird loses its eggs (eg if a predator takes them) I believe the bird eventually abandons the nest and may even move on to create a new one.
So is all the fuss about broodiness on BYC because today's hens (not
@Shadrach 's obviously) are bred to have lost that instinct to move on when a nest isn't viable? Or is it over-anxious chicken-keepers?
