Been running all my males to 2-3 females each week all season. I offer a meal to all males at the end of the their weeks pairings and the same with females between pairings. Males get a few days off, then back to cycling to other females. Sheds throw a wrench in plans sometimes.
By the time everyone is cycled around, females see a male every 3-4 weeks. Been using mainly 7-8 males and they all have 15+ locks each.... still eating and maintaining weight, although had to switch 2 males to ASF's to keep them going.
Can't say I would change a thing at this point.
