My male also stopped. I brought a doe in for the first time 4 days ago. He was very interested and mounted many times, I pulled him off the last time because it got a little violent. I separated them for the night and the next morning tried again, he now has no interest whatsoever even though she tries to get his attention and follows him everywhere. So I brought another doe for him, even less interest in her, he just lays there and ignores both of them. I don’t understand because he was so interested it was ridiculous, he would fight us to stay with her. Any clue why? We keep them all separated and always bring the does to the bucks cage, have even tried neutral ground.
