Good to know!Mine slept in the nesting boxes right up until they started laying. I tried blocking them off, but they kept breaking through my barrier! Now they lay eggs in the nesting boxes (for the most part) and sleep in the roost!
I've got the boxes blocked with 3/8 plywood screwed to the tractor frame ...... unless one or more of them turns into the Bionic Chicken, or they can summon The Kool-Aid Man somehow, that isn't going to get broken through.....
