Once you have determined a hen is broody, she must be moved to her own space, isolated from the other hens. Provide feed, water, and enough room to stretch and poop (to avoid fouling the nest). If you work with a lot of broody hens, it's a good idea to make permanent “broody boxes” which do not take up floor space for the rest of the flock. This Partridge Chantecler broody is in a unit of “broody boxes” mounted on a wall.
