We have had 2 broody set ups. The broody hen has her own enclosed area within the flock. It consists of a smaller version of the chicken set up, an area for a nest, protected from the elements and a door leading out to the chicken yard (only used once the chicks are hatched and mom is ready to deal with the rest of the flock) and a door that leads to the broody and her chicks private yard. The private yard also allows the broody to get off the nest to go in "her" yard to poo, walk around, etc. without the battle that ensues if another hen sits in her nest when she is off it. It works really well for us. We are not allowed to have a rooster, so it also helps to make sure the hen is really broody and then we take a ride into the country to Cypress Duck Farm and buy marans eggs. That night we take the fake eggs and replace them with the eggs we want hatched.
