Bucks are what has given goats their stinky reputation.
No denying it, they stink. They have good reason for it, but human olfactory systems are definitely not designed to appreciate it. Lady goats think it's the most wonderful aroma since 'Open Garden Gate', so goat folk usually try to keep the sexes separated. It's a plan that works 'most of the time'. If you notice the female madly wagging her tail and lusting after the buck pen, you can haul the buck of choice out to service her and note the exact time and date.
