Hi..i agree..you HAVE to have at least 2 goats...they really need the social interaction from another goat...honest....now, about backyards...yes!..LOL..i have 2 goats in my back yard..and i only have about 1/2-3/4 acre...i utilized my woods for them...their house/pen area is in the corner of my lot..and extends some into my woods...so, i got to keep most of my small yard intact...best of luck!..i love,love, love my goats!..
