Depends on where those females are follicle development wise. Like said above it only takes one lock but the best time to pair is when the female is already building which can take quite some time. Those are the locks that count though breeding generally is a good way to get a female to start the building process. You could definitely get her done in that time if she is building (or hope she retains the sperm until she does decided to build) but also consider you will still need to quarantine the male or risk your collection.
Quick example of a timeline for one of my females this year:
started pairing in March. No visual lock til May
May through July- paired biweekly (locks every time)
2nd week of August- cool seeking + building
while she is building I've been pairing every week and male locks her up for 2-3 days at a time. She will be ovulating any day now.
