If you are planning on close to 20 chickens, if I were you I'd just build a large pen with a net top on it. Then, build them a coop inside to roost in at night. I have 10 hens and a rooster in a 20' wide by 30' long pen that has wire around it that is 5' tall. Then over the top I have poultry netting to keep anything from getting inside like hawks, owls and coons. Inside the pen I built a roosting coop and a community laying box. Works great for me.
