This sounds like a classic hoarding case. Especially that instead of re-homing the horses, she reduces herds simply by moving some or all of the horses to another herd. So the problem is expanding in scope. And will expand exponentially if stallions and mares are in together on more than one property.
When authorities act promptly and responsibly, they can step in while they are dealing with a more reasonable number of horses, like the 6 described in the first county. When authorities delay in a hoarding case, the herd grows. Dealing with dozens of horses in distress is a huge problem for any law enforcement agency and for the rescues who try to step in to help.
Laws are woefully inadequate to deal with hoarders on this scale (or often any scale). I wish there were laws that prevented sellers from selling to people identified as hoarders. Because the hoarders never stop acquiring no matter what legal sanctions are imposed.
And for what it’s worth, every horse sold at auction is not bound for slaughter, as the article seems to assume. This fictional idea that auction = slaughter is being promoted in the horse culture by unethical businesses claiming to “rescue” slaughter-bound horses “from auction”. In fact they are just marketing horses that are not bound for slaughter. The more marketable horses “ship” to the next auction, not the slaughterhouse. They go through auctions from dealer to dealer, and finally to private owners. But the more unethical dealers are sucking in buyers who are motivated to “rescue”, including people like this hoarder.
Horses that are truly bound for slaughter are rarely seen by the public. Most true killbuyers do not have the internet resources or the time to market to private buyers. They want to complete the load asap, and ship out to get a check for $13,000 to $15,000 per truckload on delivery to the slaughter transition point. That is their business. Private owners like this lady buying from auction don’t really intervene in that process. But the private buyers think that’s what they are doing.
