The Buffett family (yes, that Buffett family) is big into farming. While grain seems to be more up their ally, operating several thousand acres of corn and soybeans, expansion may be appealing to them. Warren's grandson's VC firm is known to invest in progressive agriculture-related businesses. If the right opportunity arrived, I don't see why they wouldn't take up the opportunity.

And if we are willing to be lenient on what VC means, Warren's son is known to have invested in chicken ranches for humanitarian reasons.
