We got our two crypt orchid Nigerian Dwarf goats in May as bottle babies at 2 weeks old. We had them neutered at 5 weeks old since the doctor said it would be wise to do it young. Now our goats are around 5 months old and exhibiting what I assume is "buck behavior." They are mounting each other and they smell very musky as well as making a sort or snorting noise at each other, they also make a sound that sort of like they're saying "what." They will also stick up their top lip and pee on each other. Just recently our neighbor bought two milking goats, would this have anything to do with their behavior? Is it possible that they weren't fully neutered? We are first time goat owners and have tried searching online for answers with no help.
