If you only have 1 pair, then yes but the males will mate with multiple females when in captivity.I considered Bobwhites first, I love their appearance and the Mexican Speckled are very pretty. I don't remember what changed my mind though.
Don't Bobwhites mate for life in monogamous couples?
ETA - In the wild they will pair up with the same mate, unless something happens to one or the other, then they find another mate.
