feeding dish

Leilani, Cassy and Hero are all eating inside and that leaves Siete and Stripe outside. They don't need it badly but at least we know they're getting mineral. I was watching them eat. Siete would take about 2 bites put her foot in the dish and then go eat out of the other dish. She never dumped the 2nd dish. Then I realized the other 3 horses always used to dump their dishes until we moved them inside. Now they don't. Well when Leilani is about out she picks her dish up and shakes it but that's different. So I said let's feed Siete and Stripe on the cement. We did. No more dumping. Horses are not smart enough to do calculus but who is? What they are smart about they can be very smart. This looks like they are reasoning. As soon as they see no advantage to dumping they quit. Looks smart to me.
