We have this little old mini named Tony the Pony. He's an ornery old fart, we don't know exactly how old he is, other than probably over 15 years... He's gone from family to family to help teach kids horse manners. Because a 400lb horse can still hurt you pretty bad, but they probably won't kill you, is what my mom was saying. Also, it doesn't hurt as bad when they step on you or when you fall off since they are itty bitty. I can't keep him out of one of my chicken houses, because I open the door to let out the birds during the day and he will go in there and retrieve their feeders from underneath the chicken coop. I find the feeder halfway across the pasture.... The stinker! So he is now banished to a better fenced area. I'm not exactly sure how he reached all the way under there either.
