I know that there are a few of us in New England, and between us there are a few different breeds. I have Nigerians and Nigerian/Pygmy crosses.
Personally, I am looking to start a breeding program to get the "perfect" herd. I want to introduce some kiko into the bloodlines for more self sufficientness(they can bulk on primarily just forage), Angora to give my herd thicker coats(better for the N.E. winters), and last but certainly not least, I will be talking with a friend who has either Toggs or Aplines, about setting my nigi-pyg bucklings up with his girls for his next season's freshenings(hopefully we would get 1-3 mini-dairy doelings from him).
Edited to add: Nigerians also have high butterfat content milk, which can be made higher by feeding at least 1 cup of BOSS(Black Oil Sunflower Seed) per day.
