I know there have been many posts on this subject but I can't find any at the moment. My 30 week old cuckoo marans has been broody for about 3 weeks now. I would really like her to stop. She has taken over the favorite nest and all the other girls are upset. My top hen does chase her off so that she can use the box. I wouldn't even mind if she went broody on one of the other boxes but whenever I move her over with golfballs she comes right back. How long before she gives up. I do have a rooster so the eggs are fertile. I just cant have any more chicks.
