hmmm...well...I happen to have a banty roo, and 2 hens in an extra large dog crate in my sun room right now. They have been there for a bit over a month. I didn't plan it that way...my aunt died and I inherited them...(long story) We started their coop and outdoor run, but due to the weather not cooperating and the really short days here in Michigan (and the fact that neither my husband nor I are carpenters, by any means of the word) the coop is about 2/3 done. Looks like we might have to finish it in the Spring. The banties were raised in Virginia and we feel it is, maybe, too late to acclimate them at this point for this years harsh winter.
My three have been a pleasure. I have Stall Dry and pine shavings on the floor over newspapers. The tray pulls out for easy cleaning , and I have yet to smell them at all. The area around the cage is wood flooring and has to be swept up daily from the shavings that they toss out while scratching through for treats. I have a poop board under the perch we added and I get 1 or 2 eggs everyday.
I have 2 parrots in my living room...and these little "livestock" have been no more messy, or smelly than my other 3 birds. My parrots are definately noisier, too
He copies the roosters crow...only 5 times louder now.
My mother couldn't believe it at first. She had chickens growing up and always thought they were smelly. She is a fastidious housekeeper with with an extra sensitive nose. She is amazed that they don't "smell up my house"... lol
So...I believe it can be done, especially if you hand raise them from day old chicks.
