My first year I did the male 3 days in with the female and 4 days out. Fed on the first day out, 72 hours to rest and digest.
Now I don't rotate the male in as frequently, as I don't believe it's necessary to do it that often. This year the male goes with an individual female once a month. So, one male may be with a female a week, but never the same female more than one time a month.
