Pat after he is done, let the guy get a bit of a break. Unless you are palpating large follicles in the female already, then once every 2 to 3 weeks is plenty enough copulation, to get the female into the develpoing stage. Don't try to do too much with your males this early in the season, as you don't want them to be run down when the females start developing larger follicles (as this is when you really want to put him to work).

p.s. I have had my balls paired together for nearly 34 years now, and I would never dream of seperating them.
