Chicken equivalent of the Cat Tree?

[Siera]

I'm wanting to design something similar to a cat tee or condo for my chickens to put in their run. I have three bantams chickens in the city, so they are always in their run or coop. I'm wanting something that will help to keep them entertained and also satisfy their desire to get just a little bit higher. I currently have some smaller tree branches in their run to let them get a bit higher but I'm wanting something a little sturdier and perhaps more entertaining. But, I really don't have any good ideas as to how something like this would be designed or work. I was curious if anyone else has something similar in their runs?

I don't know that it would be more entertaining, but how about making a perch out of some scrap lumber, kind of like a mini version of a pummel horse, like what they use for gymnastics?

Dh had made a cat tree/house and never got around to putting the carpet on it. It was being stored in an outbuilding and the chooks got in there and found it. They laid eggs in the pagoda house thingy on top and it one of the towers. I thought it was really funny at the time. Our little key west roosters would sit in that thing and cluck cluck trying to talk the hens into coming into the cat house lol.
