Mine chose their "confinement" locations, and I didn't mess with either one. Buffy took over a popular nest box, but in a coop where nobody but one hen slept. They all laid their eggs there but roosted in another coop. Go figure. So there was daily traffic, but the rooster seldom came up the ramp into the coop living/laying section.
The second one, Shirley, took over a covered kitty litter box in the main coop, which I put there to encourage harmony and reduce the number of annoyed hens waiting for one of the two nest boxes built into the coop. I did not move her or that litter box out of the coop.
