keep locking them up until she ovulates you just have to wait for your female to take. i started in march and im just now bout to have eggs. its all bout environment tho. keep temps lower than normal while your pairing then after bout 2 months bump the temps back up and she will hopefully start to ovulate. its not a quick process heres a link to check out. give your male bout 3 days off after a lock then pair them up again.
