yes. I've got one loose, one in an xpen, one in a crate and one malinois in a crate when I leave. Nobody seems to feel they are treated "unfairly". I've found as long as everyone gets a cookie (or 2 or 3) everyone is happy.
Should I keep her crate in the same room Sonny spends his time (he can roam anywhere but rarely leaves his spot in the kitchen window)….. or should she have her own space away from Sonny?
You joke about one basenji letting the other out - Liyah opens both Ruby's and Brando's crates to let them out. The first time Liyah did that trick was when she was 13wks. Last night, Ruby had left a toy in her locked crate, and Liyah let herself into Ruby's crate to get the toy - she's a pistol that one!
Regarding whether to crate in the same room - I crate my 3 in the same room. I always think they like the company - although Brando will get them all going in a howling chorus.
