Just keep at it...they'll get with the program. From what I understand, the continued presence of a male is just as important to her breeding cycle as a successful copulation, so just keep plugging him into her and you'll be fine. Its still very early in the season, don't need to worry yet.

I haven't even started cooling...the girls are still pounding food like its going out of style so I figure I'll just let them let me know when its time to slow down.
