This is probably a dumb question, but a broody hen sets all day, doesn't she? My chickens free range. They are all out and about when I leave for work in the morning and when I get home in the evening. However, at sunset when I go to gather the eggs there is one hen camped out in one of the nesting boxes. She gets quite offened when I go to move her. This has been going on for about a week. Could the eggs be incubating, or should I toss them?
