Thank you for all of your advice! I finally got her into a stall ( I had to leave feed in there and go inside the house until she went in and then go and close the doors) Anyway she is easy to catch in the stall. I have left her halter on for now. I will continue with the tips that yall have given me. Thank you so much. This isnt a great pic but it is the only one I have right now.
Great advise given here. Another thing to keep in mind is...time. It seemed to take months for my mare to *really* trust me...and she was a hard catcher too! Now she walks right up...or if she's having a snotty, independent day, I drive her away. She's so nosy, she just can't stand that....
