You could make something that might work for you, but these cages have very thick diameter wire that an average person could not bend without special tools. They are made to last forever or until a truck runs over them.

Keipper coops also are collapsible ! That's what makes them so great. I can't imagine a pile of non-collapsible coops . Where would you store them all ?
We fortunately have a 40 x 60 barn where I can stack extra cages. But I also hang a few extra cages on the wall above my 10 hole nest boxes to put a broody on a nest until her chicks hatch. Or to put a broody in that I want to break brood. Because we have a tall ceiling in the barn, I also can stack a few on the top shelf of the bakery racks in the brooder room. The convenience of collapsible is great though. I have several of those collapsible dog kennels that I pull out to use when viewing birds too.
