Love ours!! We have a Marans that goes broody with the moon like clockwork!! I also have an Australorp that has gone broody once in her first season, so we'll see about next year. I have two new cochins and a silkie/cochin cross to also help with brooding next year. I will NEVER use a box again. They are such a pain!! It's so much easier to keep several breeds that tend towards broody than to keep chicks under a lamp and clean that box every day.
