I would check for follicles. I began pairing a female in December and she just ovulated in mid May. Some females take longer than others. Feeling for follicles will give you a good idea of where they are. If you feel really small follicles or none at all, might be a better idea to just wait for next season. If you feel decent sized follicles then I'd keep pairing them. The one not eating may be getting close to an ovulation. My girls stopped eating a few weeks before their ovulation.
