During the rut (bredding season) they urinate and for lack of a better term, ejaculate, all over their front legs and beards. They go at it like a 13 yo boy. Smells a bit strong, I don't mind it a whole lot, but my wife would throw a fit if I came in the house after being around the goats, smell kind of clings to you.
If you keep them separate from the girls, they will spend all their time trying to join them. If you keep them with the girls, they will they torment the girls endlessly, for they have only one thing on their mind.
Depending on the goat, they will butt/ram anything/everything in their pen, worse during breading season. I had two male goats that would destroy just about every shelter I built for them. Built one from t post and old sheet steel, another from old concrete block. Expression on the goats faces when they tried to butt it, priceless.
If you are intersted in breeding, there are usually folks around who will be more than happy to "loan" you some billies during breeding season. I have two you can keep for a while if you're interested.
Once male goats become old enough to breed at approx. 1 year, their value as a meat goat goes down. The "musk" odor tends to permeate the meat. Some Latino's don't mind but Africans are not intested. Not to be politically incorrect but they are the predominate purchasers of meat goats in my area. They drive out from the city to pickup the goats, the Latinos take them live in the back of a pickup or even a car. I have a small barn that the Africans use to slaughter/butcher the goats, they prefer to take them home that way.
