Our greatest escape artist Savannah is saanen crossed with....we believe alpine! every winter her white coat takes on very dark (almost black) markings.
The Toggs on the other hand stay put pretty much - yes Reggie has his moments if the goat on the other side of the electric fence has a full hay bag and he doesn't (typical male, way to his heart being his stomach lol - sorry boys
) but Puffin just mooches about being mellow
Have a really good trawl through this section of TAS, read the happy posts and the more serious ones but don't let the bad stuff put you off neccessarily, just let it help you understand the lessons that some of us sadly learnt the hard way. I had a very difficult introduction to goat keeping - my 4 had never been wormed or given any vaccinations at the last owner and I was far too inexperienced and lacked the knowledge to ask/check/know. As a result we lost a male kid (of about 7 months old) within a week, quite likely heavy worm burden or coxxy or possibly a mouthful of something he shouldn't when he found his way into a neighbours garden (that's when we learnt about electric fencing!) within a few months my nanny had died too due to pneumonia.
Since then I've become a member of our local goat club, we meet monthly - no question is too silly and the information and support we recieve by going is outstanding. Not sure whereabouts you are but we are in Worcestershire and I know some people from neighbouring counties come along who don't have their own club.
Some of the members breed alpines - horsehay herd I believe they are called. they have a website, might be worth having a chat?
I agree totally with Anke - find out as much as you can first, spend some time with goat keepers (if you are local enough you are welcome here anytime!)
