ooh I like that roost!! I never thought to put one in the run. I think I'll swipe some of the cinder blocks I saw in dh's junk pile and make one. I think I have a 6' 2 x 4 leftover from our rabbit hutch project.
That looks really good. I want to get one of those kennel covers for our run. It isn't chain link but I'm hoping we could somehow affix one to the top of it anyway.
