It looks like, if you mean the red-roofed areas, a horse breeding/training facility. You'd have the stalls for the mares and foals. A stud barn area, and an office. They show horses too, so one is likely an indoor arena, and a place to tie and wash.
They bred dogs too. Mastiffs and designer dogs called "pocket beagles". There's one long stretch of building that appears to have outdoor runs (I think some of these buildings are falling into disrepair). I think they still had foals for sale last year. I wasn't sleuthing them in particular just interested in the horses.
These folks are also "breed founders" of a horse breed called the Georgian Grande. I think they had other breeds they fooled with too, partly to get the the GGs. They probably toured the show circuits with their best horse(s), to generate stud fees, sell foals, and horses under saddle, to others wanting into the show business with a flashy, new, breed. These aren't horses that you'd usually see at the county fair, although some might be ending up there soon, or at rescues, if they don't have "it".
It costs to feed, breed, train, pay vets, and do upkeep on barns. Like other animals, some folks go into the horse showing/breeding business and end up broke, and practically giving them away, others know how to make it, and enjoy what they do, others create animal pyramid schemes. It seems the Ws started a new breed of horse, or got in on the ground floor. Even on a small scale, horse breeding and showing, is still expensive. Owning a single horse isn't cheap. Just this past week they did a show about the wild horses of Eastern Kentucky. Folks don't have the heart to take the family horses to the yards, when times get hard, so they started sneaking and turning them loose in the mountains. Stud meets mare, and the resulting foal grows up wild.
Some of the folks listed on the GG Horse registry, seem to have broken website links now. Maybe they moved sites, I didn't dig that far, I admit, but, it can also happen when buying into new designer animal lines. The registry fee is to be sent to an address in Piketon, Ohio. As OP said, on here, their zoo has furry pigs being donated to them now.
If anything the elders are, imo, making money off the lives of innocent animals. Being a breeder, to improve, and preserve the breed, and to keep it alive, is one thing. I'm not feeling that here. Maybe at first, but idk.
