I used to breed my males to a different female every week during the breeding season a few years ago, in the past two years, I've started introducing males a month after the start of cooling only once to every female, some copulated and some didn't.
I then wait for a shed cycle on the females and then introduce them to the males, most females were bred twice and at the most 4 copulations during the breeding cycle. I got 30 odd clutches last year and only one single slug, I see and hear people breeding their females up to 12 times, I guess that is fine BUT if you have a male that needs to service many females, aren't you afraid of burning out the males too early in the season when in fact, the last few cops before the ovulation are the most important ones.
What is the general consensus on maximising a particular male without burning him out?
