Anybody know what the maximum number of females one drake can fertilize is?

I usually hear that the normal ratio is one drake for 3 to 5 females, but I was wondering can one drake handle more than that and still have good fertility? Anybody have any experience in this area?

well to be sure all females were fertila and ur looking at a 8 to 10 female span of duck at the very least i would have 2 males for the best outcome
