Aggressive pregnant mare

My mare is a queen, by no means is she sweet and lovey. She is completely independent, but when she's on the lead rope or working she will do whatever you ask of her and do it willingly without issue. She has never been aggressive. This is her first pregnancy, she is utd and healthy. She has recently become nasty, she rears when you put a lead on her, pushes and leans on people and her pasture buddy. Literally walks into her buddy as if she isn't there. Turns her rear and tries kicking at whomever gets near her, pins her ears when I try to do anything with her besides brushing her. I'm allowed to do that much. I do not allow this behavior and I correct it when she does it, but I'm worried about this lasting or getting worse or being one of those who won't let you handle her foals. Has anyone else had an aggressive pregnant mare? How long did it last? How was she after foaling? Oh and my vet concluded it to be hormones and her not understanding the changes and foal moving inside her being maiden. And she is also not a mareish mare at all either, very independent and neutral in the herd, not dominant and not on bottom. She usually is the Robin Hood mare making sure the bottom mares get their share to eat and don't get pushed around by the dominant mares. She is due May 3rd.

Just correct her and expect her to act like she's not pregnant.
Bitchy behavior is never acceptable

Thankyou, that's exactly what I've been doing as it definitely is not behavior I want her to start now or to think is acceptable at all. Every pregnant mare I have been around has been so calm and loving and she has never been nasty.

I don't know if you already do it or not but my advice would be to keep her halter on when she is close to her due date. That way she can be caught and tied. While the foal has its first exam and has blood drawn for an IgG. As someone who has been chased around a pasture by a pissed off and protective mare whose owners "always had trouble catching her" by which they meant "we can't catch her but still want her and the foal examined". Leave the halter on because without it you don't have a fighting chance at catching her. The foal will be up and not quite coordinated the mare or you could easily knock it over in your manuvering.

Otherwise, keep the rules and reprimand her for poor behavior.

I have kept it on since she started acting up and that's another worry. I was wondering if anyone else had dealt with a mare becoming aggressive during pregnancy and whether or not she calmed after foaling. Her being maiden, I want to be sure to be nearby should she have any issues and I don't anyone including her and the foal being harmed if any intervening must be done.

Usually they get worse after they foal.
They become protective.

That's why I won't ever breed a mare like that.
My friends mare gets goofy and won't let you by it.

My mare I can't be sitting down playing with it and whatever I want and she just stands by me with her head down totally comfortable.
But she's good during her whole pregnancy.

What feed is she on? Believe it or not clover and lucerne (alfalfa) can cause this sort of behaviour. They are both very high in potassium.
Great article about this here

Correct her behavior in the least aggresive way you can. You wish to be nearby when she's foaling but she may withhold if you are. A mare likes to be isolated at this time. Perhaps if you have a box stall, just spend some time with her, even if it's cleaning a saddle outside her stall, or reading. Get her used to your being there. Do this every chance you get. Bring the other one in if you have another stall.

Or invest in a camera where she can be observed without you knowing it or foal her out in an area with marecams. I would also second think breeding her again as with a foal on the ground she now has something to protect.

I've only been around one mare that had a foal at her side. That was Lucy's mom. I don't exactly know how she was before Lucy was born but she was a B-word after. Everyone was scared of her. She even chased the vet over the wall of the stall.

Here's the kicker. I had really no knowledge of horses at that time. She let me in the stall on the third day after meeting her. She let me touch her but was very watchful when I was near Lucy.

One of the first and only the few times we took her out to a pasture to graze, Lucy got away from her and on the other side of me. She charged at me. Call me stupid, dumb or naive, I just stood there. My thought was show no fear. She turned at the last moment. She didn't kick out or anything, just went over by Lucy.
