Funny thing is, I felt that @aart was actually mildly poking fun at me with her comment. I've had others tell me how my coop build seemed to look more like a surgery suite then a coop. (Giggles) I took that as compliment too fwiw...Well that comment seems unnecessarily harsh. We all have our own preferences, skill sets, financial considerations, and access to stuff.
I have ducks and use branches of various widths and mounted at different heights.
