I use natural tree branches for roosts. I try to pick smooth barked ones that are about as wide or even a little wider than my chickens' feet, and I use some sandpaper to sand down by hand any rough edges or sharp spots. Then I spray the branch with Adams Flea and Tick spray and put it out in the sun to dry.
A chicken's toes aren't designed for gripping the way a perching bird's toes are; I think chickens are more comfortable with flatter, wider perches. I would avoid a very slick or slippery surface, too.
