I wouldn't use these for full time, but they would work great for laying cages for me. I run several breeds of hens together with RIR roos - barred rock, delaware, RIR, and sexlinks - and when I want a specific type of eggs (black stars, red stars, etc.) I cage my girls for a day or two until I have enough eggs. I think, however, I would put 2x4 uprights between each barrel set so I could hinge separate doors for each barrel. Of course, we can't see the back, so that might be how it's done. I like the durability and cleanability of the pvc. Change bedding between hens, wipe out with a bleach or peroxide cloth, and dust very lightly with DE, and voila, treated for disease and parasites.
