Hi Jaremy,
First of all, I am new at this.....but in the past my males lost interest a week or so before I saw an ovulation. This year, in the pics I posted below of Jessica, the male lost interest in breeding at least 4 weeks before this ovulation. I was beginning to get bummed, thinking it was a no go, but then she started her ovulation on Friday evening. During the last 4 weeks, I kept putting the male back in with her, periodically, to see if he would show interest. Sometimes he would crawl onto her and investigate, but when I would check back later, he would be curled up resting, or at the door looking at me, wanting out.
Good luck with those guys!! It won't be much longer
