This sounds right according to what I've been reading. I was told to take the hides out and just leave the water bowl so that they don't get distracted. Keep an eye on them, I also read that if they lock in the first day (or first couple hours in my case) you should remove the male after a successful lock even if it hasn't been three days. Then you wait another three days and re-introduce (whether its the same male or a different one).
