I rotate my males through 4 females a week one a day they all get fed on day 5 and rest for two days. So the way I do it is like this

Male - Female #1 on Sunday night, on Monday night if there is no lock. Then move him to female #2's tub. If there is a lock then he stay in till hes done, then moves to female #2's tub. So basically every female is seeing a male at the most once a week and at the least twice a month.. and I can schedule feeding for the whole collection to keep everyone on a feeding schedule. This also helps with when females are getting ready to OVY they will stop eating, and if everyone is getting offered food on the same day then I can tell who's where in the breeding process..
