Keeping a Billy Goat Around

I have some female and wether goats. Their job is to make thornbushes into meat, and maybe someday milk.

But I do not have a good stud anywhere nearby or in my network. I want to just get my own, in order to guarantee future meat and milk. However, I am familiar with the adverse effect on flavor that having a male around will cause.
Questions:

1 - If I get a male and keep him, how far apart do I need to keep him? If they are in adjacent paddocks with a fence between, will that be enough, or will it still cause all the hormones? Is it a line of sight thing? A scent thing? or something that only comes from physical or sexual contact?

2 - Is there any way to keep a billy goat "tame?" Or is that just a lost cause?

I have dwarf Nigerians.  I have no problems with having a billy.

You can put an apron on them when goats our in heat.If your herding them.Then put them back in a seperate corral.Goats our just horny there is no to ways about it.They can smell the hormones/when their ovulating.Just make sure your paddock/corral your keeping him in is strong enough.He'll probly teach you a thing or to.Goats can be master escape artists.

2 - Is there any way to keep a billy goat "tame?" Or is that just a lost cause? They our generally pretty tame.If you get one that is trying to charge you all the time then switch out billy's or butcher him. Try it get the billy goat.

I have been milking my own goats for about 10 years now. I also keep a heard of about 30 Kiko does and 3 Kiko Bucks. I keep the bucks separated not because they cause an off flavor in the milk,but because I need to know when the does will have their kids and I breed specific bucks to specific does and track the results.  In the fall, I separate the does into three herds and put a buck in each herd for breeding. I will often keep the buck in the pasture with my dairy does for months and I get no off flavor at all.  

However, I do not keep a buck that I term a "reeker"  as in he has such a strong off putting reeking smell that it makes your eyes tear up. Some of the "Reekers" will stay horribly smelly all year long.  I will not keep one of the those and I won't keep a buck that wants to head butt me either. Too darn dangerous when they weigh as much as me or almost as much as me.  Anyhow, I choose bucks that have a strong musky odor only in breeding season and even then it doesn't make your eyes water.  
So if you are going to go buy a buck make sure they don't reek. If you are buying a buckling, make sure the sire doesn't reek.

Keeping bucks away from does is hard.  I had to build a double fence that has 3 to 4 feet of space between the buck fence and the doe fence or they will just go nuts in breeding season and bash the fence until their head bleeds. I have had them break through wood fence, cattle panels and even bend a heavy duty metal cage panel that they use in warehouses to keep goods locked up.  I had to drive over that panel with my tractor to bend it back in shape.  And they can suddenly jump much higher when they are in rut.  I also run an electric hot wire on the buck side of the fence.

If you are keeping the buck with your does you won't have that problem.  Some bucks are great with the kids and wethers, some bucks will not tolerate them when they are in rut. I had a buck named HOss that would heat but other pregnant does when he was trying to get to a doe he wanted to breed. Needless to say that caused some problems so you couldn't keep him with pregnant does or kids if there were other does in heat.

Do not ever "play" with a buck or buckling by pushing on their head or whacking them on the head up by their horns. This can cause them to think you are fair game for headbutting.  It might be cute and funny when they are little, but when they are 50 lbs or bigger, I have some up over 150 lbs, it can get you hurt really badly.  I have three mature bucks right now, none of them try to head butt me.  If you need to get goat to stop head butting you don't ever hit them on the head up by the horns, whack them in the nose. That will usually stop them in their tracks. Had a big buck eyeball me and I wanted to nip that problem in the bud so I got a piece of PVC pipe and the next time he did it, I whacked him right on the tip of his nose and it stopped him in his tracks. He shook his head several times and walked away.

anyhow, good luck! Goats can be a lot of fun. Goat milk is awesome. If you get a doe with funky flavored milk get rid of her and get a goat that has nice flavored milk. I have only come across two that had funky flavored milk. All of my other girls have wonderful milk that tastes great!   Goats can also drive you crazy. LOL
