Hi Karl, yes I am one of the contact persons for people interested in buying Golden Guernsey goats, mainly for Scotland and the North of England though.
The way it works is that anyone from the GGG society who has stock for sale tells me about it and then I can mention this to anyone interested (and wihtin reasonable distance of course). However the GG's have become very popular, probably due to some person repeatedly putting them on TV....
, so lots of enquiries but not many for sale I am afraid.
If anyone is seriously interested in GG's the best bet would be to become a member of the GGGS and then you would have access to the address list, and you can then a) visit GG breeders to talk to them about stock and goatkeeping in general, and b) you would also get a whole caboodle of info on how to keep GG's, breed etc etc - really, really useful stuff for any novice goatkeeper.
Another place that is now used by quite a few breeders is
www.ukgoats.co.uk - but of course with all the usual caveats of buyer beware etc etc - one thing though: if you are looking at some goats in particular ask the seller for their registration numbers and get back to me and I can verify them for you. DON'T EVER BUY A GOAT (and the seller teling you that - THE REGISTRATION PAPERS WILL FOLLOW) - they quite often never do!
Of course, if you are ony interested in milk for the house, registration with the BGS is not necessary, but again make sure that at least the sire/father is registered, and that you can preferably see her dam/mother too - you could otherwise end up with a very poor milker indeed...
In the UK only goats up to 24 months of age can be registered (and only by the original breeder) with the BGS, unless they go into the identification register. So if anyone offfers you a goat in milk and tells you s/he will be registering them for you - cannot be done!
