Well, my new boy has been showing aggression toward people around food, hay and grain. It started with my husband and now he has shown aggression toward me. He hasn't bitten or kicked, just put ears back. BUT, tonight he put ears back and came torward me a little... I chased him off and he showed more aggression (turning to kick)... I didn't have a whip or I would have really gotten after him. I yelled, waved my arms so he just went and chased the next in pecking order horse (my other gelding) off their hay. SO, is this a common problem? If I get after him, I imagine he will stop doing it toward me, but will he do it to other people still?? When I work out of town, other people (my hubby, my neighbors) feed for me... neither of the other two show aggression like this. I check them all while they are eating their grain usually.
