Because I know that integration into a herd is tough, if I take one*, I'll be taking both. Goats often socialize on the buddy system - look at Betty and Pansy together vs. Lily all alone - and will have a lot less stress if they have a friend. *And who am I kidding? I'll be taking both.
With Lily and Richie, Betty and Pansy, and these upcoming goats, I'll likely not have to buy goats for a long time. In fact, in order to keep my winter stress levels down, I'll have to get rid of some goats by next fall.
