The kids have collars but have not been on a leash yet. I took them around the pasture to see how they would do with the leash. To say they were not happy was a gross understatement! They dug their hooves in and pulled back and said no I am not going anywhere with you. So plan b pick them up and carry them into the pasture this just changed the location but not their attitude. We will need to work on this some more!
