I was never worried about my male. The prego girls were fighting hardcore and my male getting caught in the middle. I didn't want any of them getting hurt. That's why I separated them. And the fact that I did not know if they were prego by him or another male back at the breeder's where I got them from. I prefer to know who's is who's. LOL
Sorry bout the problem with your females. I am not experienced enough to give any advice on that. But someday...
