You need to progress through stages, firstly go into your horses field when you don't intend on catching him and get him used to you just being there. Do this a couple of times and then start giving him treats in your hand and stoke him but still don't catch him.

 Once he understands that you're his friend introduce a headcollar but still give him treats in your hand, everytime he gets a treat make a distinctive noise, like a clicking or a whistling, eventually your horse will get used to this noise and he will relate it to a treat.

Once your horse is fine being caught with a treat try catching him without a treat but still make this noise, he will eventually forget that he will recieve a treat and will just think the noise your making is a good and comforting one. Evetually you will just have to make this noise and your horse will come to you.

However this does not work overnight it may take a few months for your horse to be confident when being caught. Hope this helps x

tried everything guys shes just very naughty kicked me the other day were going to sell her or give her away i have to say shes a gorgeous mare and would do very good in the right hands but i am not and experianced handler and do not have the time as have 3 other horses to look after

but we are having stabled built so i will get her into a stable and mess with her for abit see what happens after then thank you for taking the time to answer my questions xx

agree with the above, u could try and leave the headcollar on her in the field as long as it doesnt rub and fits right, as nervous horses can get scared of the headcollar strap coming over the head, i know my timid mare can be a little funny sometimes, it also means u can hide the leaad rope more easily, and the more confident she gets will mean u dont have to leave the head collar on.
