Right. Separate them when they unlock, give them a week or two (or three) apart, and then back together for three days or lock, whichever is shorter. People always reference the 3 in/3 out "rule," but that applies to the male when you're pairing him to multiple females. A lot of folks on here agree that a female doesn't need to be locked more than once a month by the same male to produce. Congratulations!
