Very nice!
A couple of thoughts. When I use natural branches for roosts, I run my hands over the branch to make sure there are no rough or sharp spots (especially where I've trimmed off other branches) that could cause abrasions on a chicken's foot...that could lead to a bumble foot infection. Where I find rough spots, I sand them down really well.
The other thing I do is remove any visible mold or fungus, and then give the branch a good spraying with Adams Flea and Tick spray. Then I sit the branch out to dry well in the sun. Mites from wild birds sometimes hide in tree bark or crevices in the wood, and I don't want to add critters like that to my coop or aviary.
Finally, make sure that the tree you pick for your natural roost isn't a toxic one. This applies more to perches for other kinds of birds than chickens, since chickens aren't wood chewers the way parrots are.
