Yeah, that's kind of what I am doing but I have not ever seen anything like this. Same proven male for 2 seasons 2-3 times a month good locks and what I mean by this is I have been breeding her almost every week for over a year. She went off food in December for a month was pretty sure I had an ovy then nothing. The boy is at 1300 now and he has never went off food. My other girls at some point want nothing to do with the male. Not this one. She's like the energizer bunny. Just no babies.
