Hello Lisa,
Welcome to the forum!!
I have had goats for 35 years, and have had most breeds in that time.
Personally I prefer the bigger breeds, the Anglo Nubian, British Alpine, British Toggenburg and British Sannan. These are large goats, and can give a lot of milk per day.
For people just starting out, I think you should be looking at the smaller Sannan, and the Golden Guernsey would probably suit. Newly kidded, these would give you ample milk, amd being smaller, they are easier for novice goat keepers to handle. All goats can be strong, but the bigger breeds especially so when you are leading them. Also, the smaller breeds are more suited to smaller plots of land.
Pygmy goats are gorgeous, and nice as pets, but if you want the milk, then these are not the goats for you.
I had bred all my own goats, and when I came to buy a nanny, I was gob smacked at the prices being asked. We do not see many goats for sale here, and any that are, are sold immediately.
