Hi, I'm Mags. A while back ago, I bred a pair of my New Zealands and had a litter of 7. We raise for meat and butchered a few kits from that litter late because we had a lot going on in past months. We just never got to them because I've been at school, and Mom would rather have us sell them to 4h kids. It hadn't donned on me how long we had had them. They are now 5 1/2 months old. I have 3 does and a buck together. The buck is showing genitals, but I don't think his testies have dropped. He has not shown any sexual behavior with the girls that I've seen. I have separated them. Do you think I should be concerned about pregnant does? And at what age do NZ bucks become fertile?
