I had another one as well but now I don't anymore. One of my Bresse hens from my breeding group went broody a couple of days ago. They have a roll away nest box so she was sitting on nothing.
When we built the nest boxes I designed them so they could be convertible in case someone went broody so the floor can be made flat. In their roll away state, the nest boxes have artificial grass and no other bedding. The newer ones like my Bresse have can also be lifted out so a broody hen could be moved into a new area without having to leave her nest. (My other broody, Moonsparkle is sitting in a fixed in place nest box in one of my older style coops. It's also convertible but it doesn't lift out, unfortunately.)
I thought all of this was a great idea but hadn't tried it yet. So yesterday, when she came out, I changed their nest box to being flat floored and added loads of wood shavings for her. Not only did she break from being broody but now all of the hens in there are avoiding the nest! They are terrified of it.

The cockerel has been up there clucking at them today so hopefully he's telling them to stop being stupid and just use it!
I wonder what the chances are that if they get used to it she'll start sitting again? And if they break that easily, will it even be possible to follow my plan of lifting the whole nest away with a broody in it?
