I have 5 chickens in my house at the moment, they have been in here for several months. one because she is the wrong size to go with either of my coops and 2 sebrights because I hatched them in incubator too late to put them outside and the last 2 d'Anver hens because they were rejected by my sebrights outside. I built 3 cages out of pvc pipe and deer netting, they have multiple floors with peel and stick floor tiles. I put a little straw in their nesting area(cat hidey hole with shelf) and that's all. very little dust and almost no smell. their cages are swept/scraped clean daily and the mess is minimal. I tried before with bedding and the smell and dust were awful. they go outside daily to play in the 10x10x5 run(also of pvc & deer netting) and are quite happy in their cages, for now. I used the pvc and net because it is cheap, easy to build and move. I do use an odor absorber sold in the cat litter area.
