I LOVE chickens but I too would hate it if they pooped on my deck or patio, they don't belong wandering all over people's properties. My hens have a fenced in 1/4 acre and they stay on that and that is where they belong. I wouldn't want them in our part of the yard. That part is for us to enjoy poop free. I'd recommend a good large fenced in area with some sunshine, some shade and some greenery. Hope you can accommodate that. Then everyone will be happy, chickens included.
