Mine don't,just 3 coops built to 1 coop, their was a hole from the chickens 2 parts of the coops leading inside their coop. The guineas sleep in the nest boxes since they don't know what they are.. I give them roosts in the run but they don't use them. I have a nice secured run with a tin fenced roof, hardy fence that foxes and bears have attempted to break down and have yet to succeed and tons of branches for them, they'd rather sleep where the chickens lay their eggs.Mine share everything including nest boxes.
