There could be several factors, she could be approaching ovulation, she could be gravid, she may have absorbed follicles and no longer cycling, he or she could have lost interest. Wait for a good storm system to come through, they are usually more responsive when there is a low pressure system. They also could be locking and stopping quick, I had a pair that I never witnessed lock yet they produced eggs and babies. Just keep trying until you see an ovulation or eggs![]()
