In learning to train a puppy/dog is by learning from a professional. So when I needed a PT I chose an 18 month old dog to adopt as I was suspected of being terminal. My wife & I disagreed on how to train her so she adapted 2 ways to mind. My wife barks orders & our dog acts like she is in basic training & obeys to commands abruptly. I chose this other way of using treats to get her to do/not to do things up until she does it for the praise alone afterwards. Both methods work. Here's a link to the professional that I learned from & he has other youtube videos as well. The one on how to get them to ignore outside influences like other dogs are also there & just replace the dog in the video with your chickens.
