Is this a good choice?

so, i am thinking of adopting 3 or 4 (or more, i don't really have a final # yet) pygmy/nubian goats. i was thinking fo getting, if i got 3, 1 female pygmy and a male and a female nubian. if i got 4, then i would most likely get the same combo as if i got 3 goats, just with one more pygmy--not sure of the gender yet. should i do this? and can you back me up on some info? i an buying property on St. Croix, USVI so that's where they would live. good?
