mmmmmh.... difficult one I think

I was under the impression that you don't have a choice. But I am in Scotland, and so far no TB here.
When the outbreak happened in the Golden Guernsey herd it caused a lot of heartache as goats had been sold from the initial outbreak farm (it was then thought that goats cannot get bTB, and to date I think the only outbreak has been in GG's)....
But humans do get bTB too, so another thought to consider... I normally get quite close to my girls, and the goat kids have no manners like "hand-in-front-of-your-mouth" when coughing, even when jumping up to me (and my human kids). I would probably be worried sick that my human kids could be getting infected, and for peace of mind have the goats tested.
But if the goats test positive....
Your vet will be the best person to advise. Do you know any other goatkeepers nearby?
Re male - I would go with a Saanen type, but then most will turn out white...
