I've heard stories of bucks breeding sisters and mothers at five weeks old, but I have three new bucks about 12-15 weeks old, and even though they've been with their girlfriends for a couple weeks, none of them show signs of pregnancy. Are my bucks too young? Are they too shy? Do they need to watch an after school special to know what to do? I just got rid of my one breeding buck, making way for the new stock, but so far the new stock is sort of... limp. How can I help my boys???
