In your experience is one lock enough? I have a male first year breeder and he had bred three females so far. I am putting him with a female for three days and resting him for three days. He is still eating once a week. All three females he has locked up with within hours of being placed together. After the first lock with both the first and second female he was given a break and showed no interest when placed back with them. He is locked with the third female now for the first time so I don't know if he will show interest in her the second time around or not. All of the locks have been 15 plus hours.
