Can you modify behavior in a bully?
Up until 2 mos. Ago, my herd consisted of 3 geldings. Our paint, Tahoe is the boss, then our POA, Spirit and then my 5 yr. Old draft cross gelding, Cody is at the bottom. We added 2 pony geldings to the herd as companions and everyone gets along except my draft cross. When I try to turn them out to pasture (they've been living side by side in electric fencing pastures for 2 mos) everyone settles down to eat except Cody. He's like a pony-seeking missile, chases the ponies allover until they run through the electric fence to get back in their own pasture....... When I first introduced them, the smallest pony (11 hds) went prancing up to Cody (18 hds), squealing and striking. Cody looked a little surprised, swung his head over and looked at me, then turned back, laid his ears back and proceeded to chase the pony in circles around our orange trees like a freight train. Scary! I've put him in his rope halter and fed him next to them, disciplining and isolating him until he can eat nicely but as soon as I turn him loose, off he goes. Any ideas for how to bring the peace back to my pastures? Right now, I can either turn him out with the paint and POA, or isolate him and turn everyone else out but him...... I was hoping my other two geldings might get after him for acting so a-social but they just busy snarfing down grass...... My feeling is that he's been bossed around for so long, he's thrilled to have someone to boss around but he's taking it too far and playing the bully. Makes me wish I had a shock collar with a remote for my horse! Normally he's very friendly and submissive.
