I feel your pain!
I only have 2 but boy oh boy, they can poop up a storm on the porch, especially the hen. The roo's poo is much more modest in size and isn't messy like hers.
During their free range time you'd think they'd explore the universe but no, a goodly part of the time there they are on the porch staring in the door! Sometimes one at the front door and one at the back door - quite the sight - a chicken at every entrance.
I am trying to make sure I don't feed treats in those spots but admittedly sometimes forget.
Assuming I mend my ways, my hope is that they will spend less time in these spots though sometimes I am glad they are there because I think a hawk is less likely to bother them right at my door. But then there's all the poop. I was thinking today how the front porch must be refinished this year (mold, mildew) and then when it's nice and clean how much worse it will be when there is a poopfest.
Sigh...............
