Yes you can breed multiple females to one male . Start with one female, leave him with her for 3-4 days. Then give him a day or two off to rest or feed ect... Then place him with the next female and so on . Even if you don't see a lock with one of the females after his resting period move onto the next female. Just watch all the signs of OV. After one female OVs then you can stop paring them.
