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?
