Hi Teresa,
I like your taste- Anglo-Nubian's are of course the best kind of goats there are! I have 10 at the moment (eek thats a lot- must cut down!). One of the best ways to do some research, is find some goatkeepers who live nearby, and see if you can go visit them (ideally a couple of goatkeepers). That lets you see how different people keep their goats, some people have acres of land, some keep goats in a little backgarden. There isn't a right way or wrong way of keeping them, you need to develope a way that suits you!
Little blue mentioned CAE, I would recommend you try to get goats which have been tested negative. They are like sheep in that they need wormed, if you live in a fluke area, they could need dosed for that twice a year. Also, there is a vaccination which helps to protect them against various diseases. There are a couple of different brands, Heptavac-P and Lambivac are two of the vaccine brands.
Anglo-Nubians don't give quite as much milk as some of the Swiss types of breeds, and they tend to have more kids than the Swiss breeds as well. Triplets is not abnormal for them, and quads are fairly regular, with some goats even having quins. However, it should be possible to get some milk for you and some the kids. Again there are different ways of doing this. You can take the kids away from their mother, hand milk the mum, and bottle feed the kids. Then you can keep some of the milk for yourself- as long as they are producing enough to feed the kids. Or you can leave the kids on their mum's, and wait until the kids are a few weeks old, then shut them away from mum overnight, and take some milk for yourself before letting the kids back to her.
Most importantly, goats are herd animals and need company- you need more than one, or they have to have something to live with, a donkey, pony, alpaca etc. And, they need shelter. They are not like sheep, and cannot live outside with no access to shelter. They need access to a shelter, from heavy showers, and cold weather.
Best of luck- if you are looking for some contact names, I can probably find out a few for you. The Anglo-Nubian Breed Society is good for some contact names too.
