I know that Nigerian bucks are way smaller than Nubian does, so when people decide to breed them for minis, how is this done? Can the buck reach the doe? I have a lady that really wants to breed her nubians to my nigi, her girls are bigger, but he bred a 7 year old nigi that was bigger than him. I heard that if shes in heat, he will find a way no matter what. So is this possible?
