Any horse/farm supplies (Moorpark)

I am interested in any extra supplies you may have that would work on a small farm, including supplies for helping teach kids about animals. Enrichment for the horses like jolly balls etc or even water barrells. I am in need of pretty much everything for a summer camp farm experience. Thank you in advance! We have goats, pugs, alpacas, sheep and horses, and no money per usual 😝
