I had to keep a billy as there are few goats up here and only a couple of billy goats and so they are all related. When a neighbour of mine brought a billy up from Orkney but then could not keep him I leapt at the chance of having him. He is a gentleman, he is in a stable next door to the females and runs with them during the day. I have no alternative yet and have had no problems with smell but he is the only billy for about forty miles one way and you have to go to another island to see the other billy up here!

Female kids can come into season the Autumn after they are born.  I had a pygmy accidentally get in with the billy at six months, and she had a single female before she was a year old.  So, yes, the youngsters can  be active from an early age.

Yes and unless he is castrated the meat will be tainted with billy too...
 
However I know lots of people keep their boys in the same shed as the girls (behind sturdy metal hurdles though), and the boys go out at night time. It seems to work and haven't heard of any issues re taints in milk.
 
Even if he doesn't get the female kids into kid, he will still constantly bother them, I have a couple of wether kids and even they jump (their sisters mainly...)..., so both my boys will go as soon as reasonable size.
 
I am planning to keep a couple of boys intact next year, but take them off the nanny and bottle feed in a separate pen, even away from the female kids form the start.

Billy now seperated, down with the 2 wethers. Actually it's nice to have the girls back up in the barn, tho they aren't happy, they are used to being able to be in and out as they like, lotof fencing and rearranging before I can do that withthe barn  .
Someones been telling me how she used to make a little 'apron' out of leather for her billies, so they couldn't actually make contact. Any thoughts?
 
Hermit - isn't it so windy up there the smell is whisked away?
