I was wondering, how many copulations do you usually witness (I know they can do it while you're not looking but sometimes you catch them in the act) in cases where you get eggs? Do you have pairs that copulate a couple of times and just don't drop?

Is it true that sometimes one time is all that's needed for consequences, or are you confident in expecting eggs only when you know they've copulated at least x times?

I have one pair that has copulated 9 times this winter (as far as I know of) and another where I've witnessed a lock only 3 times. Still no ovulations witnessed though... Only some bowl wrapping by the first female. What are my chances of success?
