We recently added a 4 year old red heeler/border collie mix female to our family. Her previous owner said she was miserable after moving to town and needed a home in the country. He said she stayed out of the road for the most part and that he was not sure how she would do with chickens because they did not have them. They rescued her about a year ago from the pound and had her very well trained. He said she would keep the coyotes away, etc. We have had her about a month. A day or two after we brought her home, I tried her off leash and she ran to the road, chased a car for a second, and went exploring the property across the road. She did return when called, but it took a couple of minutes. The next day, I decided to take her out with a few treats in my pocket and see if she would stay relatively close to me with the chickens locked up in the coop. I was not aware that one hen had decided to roost in a tree, and was loose. She chased the hen, caught it, and the hen lost some feathers and hid until evening. Since then, she has only been outside on a leash or long line. We have been working on "leave it" and I have had her in a down stay multiple times with the chickens wandering all around. She stayed pretty focused on me even though they were close. She is definitely less interested in the chickens and knows they are not to be messed with,but her ears perk up when they make a lot of noise or go running across the yard. Her manners in the house are excellent and she stays inside all day while we are away with no problems. She does have good impulse control as far as waiting for permission before eating dropped food, etc and knows we are in charge. I ordered a training collar from Amazon with a beep and 100 levels of shock and vibration. We figure that as smart as she is, it will probably only take one or two small zaps to keep her away from the chickens. We would also like to teach her that the road is off limits too. I would not trust her alone with the flock, but would like for her to be able to run around and dig up moles, etc. Does anyone have experience with these? Should I use the beep as a warning before shock or vibration or reward her for coming to me if she hears it? I think most people use the vibrate to warn, or it is sufficient alone. Of course the directions that come with the collar are not great. She is a super dog. I don't want to totally stress her out, but I also don't want her to have to live in the house all the time if she loves to be out, or to be hit by a car or shot by a neighbor for chasing their livestock. I would appreciate any suggestions. Thanks!
