That is where I saw it also but decided I wanted something bigger to hold more birds.
This is what I am using for my pigeons. I have V perches, nesting boxes, bobs and an aviary all on it now, and 35 pigeons in it. Hopefully to be a lot less real soon when I start using some. Some of my buddies thought it was going to get too hot in there but even in 100 degree days it isn't all that bad in there. I drilled some 1" holes in the floor for water to drain and if need be just go in there with a hose and let it have it. I think this weekend I am going to divide it so my shooters can be on one side and homers on the other. Real pain to try and catch just certain birds.
