Hello, tree farmer,
Go for it! You are ready to milk, and AN milk is usually a bit creamier than swiss breeds, so should be wonderful for both cheese and soap...
All of us livestock keepers have animals get ill or die at some time or other, and I think in almost all cases it can be traced back to a human mistake - mostly that human is the keeper... You are annoyed with yourself and every time question yourself and your ability to look after animals, but then you go out and it's feeding time/lambing/kidding and things are alright again!
Only one word of warning - a) goats are addictive, you may start out with one milker and a companion, but once she kidded there will be a couple more.... etc etc you get my drift. I started out with one milker and her kid, plus on goatling. I now have 5 milkers, 2 goatlings and this year so far 4 kids... one more nanny to kid though... and I love them all ot bits (most of time, except when they again pull my hair, trample all the hay, trash their water buckets.....) and b) AN's can be quite noisy goats, so if you have close neighbours make sure they don't get too annoyed with the noise.
