Background - ex racer off the tracks bought to become a broodmare. 4 yrs old. First month spent rearing in a blind panic but gradually calmed down and for a while became a doddle to handle. Usual scenario of gaining condition and becoming a bit more confident. Showing aggression in stable (kicking,biting). This we've dealt with by usual stuff, making her move over, tying her up to rug and in extremes a slap to the neck when shes been downright vicious. Behaviour has not improved greatly but been manageable. However my gelding (who was top horse in field) has been away for last 3 weeks having some schooling and she has become top mare. She's beome hell! Today in the field when I went to check rugs she launched herself at me, snaking her head teeth flashing. I made myself big, jumped up and down like an idiot bellowing at her in an effort to send her away but she kept on coming until she cornered me and tried to double barrel. Same thing happened to my other half who went in later (I've never seen a big bloke move so fast!) How do I now deal with this? Show her more aggression ie go in with a lunge whip and if she doesn't move away from it then as a last resort hit her? Or is this just going to fuel the aggression? How to you cope with a horse that doesn't back down? We keep her at home so its just me and OH to deal with her. I've never dealt with a horse that you can't send away from you, she just keeps coming no matter what!! HELP
