This is going to be kinda long but I want to make sure I get all the details! I've never delt with this so I have no idea how to deal with it.
Lately since my 3rd horse came home[about 2 months ago] my 3 almost 4 year old mare has started bad food aggression out in the pasture and in her stall.. boarder line dangerous.
If she has a halter on and knows the human is in control she wouldnt even THINK about biting or kicking... she's broke, and very well mannered .. its when the halter comes OFF its a little scary. It confuses me.
I don't worry about myself I worry about my students, and my step daughter and husband who arent horse savvy. . .
A few examples:
Today my working student was just walking through that pasture past Jovie and her hay.. the ears when back the head came up and she charged him and miss biting his should by an inch! I ran up chased her off hard and fast till she gave me a better face.. then I let her have her hay back..I don't know if this was the right thing to do but I've never delt with this so im LOST beyond lost.
A week ago when I was messing with her blanket in her stall while she was eatting hay.. she was fine then right before I was done I just saw the ear pin and a head coming at my face.. I swung and belted her in the face .. pure reaction.. but still I was shocked.. 2-3 months ago I use to be able to groom her in her stall while eatting, blanket and just fuss with her.. whats happened?! Now if I had a halter/leadrope on her she would have stood there like an angle while I did that.. :\
She's now in her own paddock due to needing to be on a diet .. and its seems to be only getting worse in the pasture.
I just don't know what to do.. she's such a good mare when being ridden and handled with equipment on.. id hate to have to sell her cause she's not safe otherwise.. hoping you guys can help. I've had her since she turned two.. she's almost 4 now.. she's never been starved... mishandled.. she's always been made to behave.. not spoiled.. I don't know where this is coming from. All treats were stopped long ago unless she does something amazing during ground work.
