TURN OUT more over stalls saves bedding/shavings
COVERED Round bale feeders if you offer hay in the paddocks/pastures
Hay Saver nets seem to work but the hay needs to remain in a covered area in my opinion
Instead of squares, feed off of a round bale. Fork it off.
Lock down your hay price/amount with your hay dude/dudette
Feed individual horses to individual needs. Offer a "flat rate" for up to x amount of grain. Additional bring your own or x amount per pound. (I calculate a 1200 lb horse's grain needs. I offer that for the standard rate, regardless if they need less).
