And the flat vs round debate goes on. I figure the modern chicken is basically a domesticated jungle fowl, which have evolved/were designed to roost in trees, and trees rarely have flat limbs. Makes sense to me.
I used a wooden stair rail. I roughened the top a bit with a course sandpaper so it's not super smooth and too slippery for the birds
The width is about two and a half inches and their feet fit perfectly across the flatter top, their talons just curling around the rounded sides. When they sit down their feathers cover their feet completely so they stay warm.
The downside is it isn't as cheap as a 2x4, definitely not as much as a tree branch gathered from the forest.
