How to halter train a new heifer

[KevinN]

Well I got a really nice Murray Gray from Hays at Backbone Ranch about 2 weeks ago..Thanks Hays! She is due to calve in March. I have her in a 50 x 50 barnyard and stall. I would like to get her calm before she calves. She will come to a bucket of corn for a few licks now if I crouch down and hold the bucket with an outstretched hand...I try to do it daily. She won't take a treat from my hand yet and is still kind of skittish. Any tips for how to move things along? Kevin
