Would it be absurd to keep two female coturnix indoors in a guinea pig cage? They seem like bird equivalents to guinea pigs size-wise, not too large as long as I avoid the jumbos. My buttons do very well indoors and cause no trouble at all, but I hear coturnix can have more smell? I really keep up on cleaning for my indoor animals like a full time job (that I enjoy) but I don't want anything that's going to really reek. No outdoor space at all here...
If I got cots I want to hatch and socialize chicks so they are tame. Though my buttons have gotten very friendly just through mealworm treats every time I open their cage.
