Hi, Well as long as she continues to lock up with males I will keep trying. Some females just develope late in season. If she stops locking up, shows no interest in males and is not building follicles then you could stop ipairing her up. Me personally will continue pairing as long as the female is receptive. Sometimes you don't think she will take and then out of the blue she will ovulate or start building late in the season. Good luck with her..
