Running away from me!! :(

OK so, I got my new mare in augest, I LOVE her. But...
She has started to trot away from me in the feild. It is a HUGE feild and I just cannot chase her around it because I would never cacth her. I do not want to bring a bucket of oats with me when I go to catch her because there are other horses and they would swarm me .
Does anyone know another way to try and catch her? I always bring treats with me, I have even tryed slowly feeding the treas to the hroses beside or around her to try and get her to come overto get some. But she outsmarts me, she pretends like she isnt paying attention to me so I try and walk over but she trots off, it is only at a trot right now, but I wouldnt liek it to escalate to a canter/gallop away from me. I want to fix this problem as soon as possible.
Any ideas?

Thanks :)

Try giving her licorice everytime you get her, and everytime you let her go. You will soon have her running to you when you come out

lol she doesnt like liquerice :P but the problem is she's not treat or even food oriented at all, she has actually rejected oats from me once, and she's very specific about apples, but she likes carrots. I always bring treats, but she still runs :(

Oh that sucks, my horse loves it, that's how I taught her to float lol

Haha ya my first horse would jump a house for some black liqourice! But rena is just so darn picky, she even spat out a homemade horse cookie right in front of the chef! Lol

Haha, that's funny. Lol, but makes things hard maybe you can try getting her into a smaller yard or paddock and work from there?

Thats a good idea!! But sadly we can't right not because all the smaller pastures are full :(

Maybe try holding the halter and lead behind your back so they can't see it...also move slowly over to them. Don't let them feel like they are being chased because then they will run! Especially in the spring when the grass is green and thick they never want to be brought in. If my horse is running from me I try and get him into a corner or I use other horses to block him into a area where I can get him. Remember to always give praise if she comes to you right away and even after you halter her!
Good Luck!

Throw rocks at her in the mean time? That'll make her love ya...

bahahaha that made me crack up! that is definitely what I wanted to do when it was minus 25 and she was running away from me. I will try hiding the halter behind my back... or I could do like you said, and throw rocks at her until spring.
