I have 4 Coturnix in a bin cage in my house because the albinos can’t live outdoors. It all depends on the feed. I used to clean out the bin fully, once per week, and sprinkle fresh chips on every couple days in between. They were still a bit stinky. I switched them to Hudson feed gamebird pellets and I can basically mix the bedding twice per week and add extra, and only fully change every other week, and there’s no smell besides the pine bedding smell. It’s really a miraculous difference, I really only need to change it because the bedding gets high and dingy looking. I’d assume a couple buttons will be less messy than 4 Coturnix.
I find many feeds make stinky poops, and often if you read thru all the reviews, you’ll find some commenting on that. Homestead harvest, southern states, and HH feed all make pretty equally smelly poop, but it’s different flavors if you know what I mean. One smells poopy, one smells like rotting fruit, etc.
