What's the best if any way to tell how long it'll be till ovulation? I've got a couple females that have been locking with their males alot over the past month and their follicles are getting bigger by the week. I'd say they are the size of big marbles ( the smasher or whatever they're called ).

Anyway if there's a way to tell that would be nice, but I've also heard that you can only sit and wait.

Thanks
Dustin
