i have the opportunity to buy a pygmy doe and her twin pygoras a doeling and a buckling for a 100 bucks and am wondering if this would be a good investment. i'm really looking to get a dairy goat but was thinking i could keep the lil doeling to keep my future dairy goat company and sell the other two and break even on the purchase of my companion. how big do these mixes get and would they even work as a two person dairy goat since some people use pygmys for milk would the larger angora up the milk production some? thanks
