Personally, I would be very reluctant to lock my 17 up in a coop. I think they have a better chance against two- and four-legged predators if they unconfined. So, mine are free to come and go as they please, and they all come home to roost in the coop at night with the door open, except for Iris when she is brooding and/or has a chick--she prefers being under the brush in the ruin, and Agatha chose to nest in my bedroom on on a platform I built for the cats. Bertha also brought her chick up in the ruin, and then once old enough, took her to the coop. Once her chick is old enough, I am sure Agatha will return to the coop, as will Iris.
I have plenty of bushes on my land for them to hide under when the aerial predators are around, as well as open horse stalls and a carport where they gather in the rain or if they see predators, and I am not afraid to chase the aerial predators off if I see them and tell them this not the Kentucky Fried Chicken. I have managed to develop a relationship with the crows (they worked together and got two chicks initially), and the dogs and cats are disciplined severely if they show a predator interest. Also, the three older roosters keep the hens company.
I know giving them their freedom risks their loss, which always hits me very hard, but I believe in quality over quantity. My neighbor, for fear of loss, has her three locked in a coop that cannot be more than a meter square 24 hours a day, and after seeing mine, she let them out, and they were fearful of the open space. I would rather not have chickens if I have to imprison them.
I eventually figure out where the clutches of eggs are when the hens come out squawking for a dust bath, and I follow them back to find the eggs. At the moment, I am allowing them to breed just single chicks, in other words, collecting all but one or two eggs, because the flock is proliferating beyond what the size of the coop can accommodate.
My car might have to give up the carport so that I can extend the coop if the flock becomes much bigger.
