I have 5 broody hens out of 12. They weren't in the nest box, but were huddled up together in a corner. They have been sitting there for the better part of 6 weeks -- no chicks -- probably because they spent too much time fighting over the eggs. Well, I have had enough so I gave the coop a good cleaning, took all the eggs away, and put a plastic recycling box where they had been nesting. When I let them back in (they were locked out while the cleaning took place) they were not happy. They finally decided to brood in the new nest box. It was so funny watching them all try to pile into the box together. Here is a picture of 6 of them in the box. Five are broody and one laid an egg.
