So I just tried it, here's how it went: So I started by letting all my hens out into the yard, and then I let my dog out, e-collar on and set at 50 (for reference, his usual corrections for day to day things is 21). I casually walked out with him (off-leash), and I was just standing around and sitting about. One hen in particular was following me around. At this point, Ranger (the dog) is steering clear of all the chickens, but that's just because I was there. I then got up, went inside, and hid and watched by a window. Now that I am gone, Ranger is showing more interest to the hen that is by the door I just went through. He starts putting his head low, and trotting towards her (not a full on chasing run, he was only moving closer to begin the hunt), as soon as he moves towards her, I tap the e-collar. That stopped him dead in his tracks. He gave out one yip, and then sat down, looking away from the hen. Maybe a minute later, I walk back out again, ignoring Ranger. Once I get away from the hen, he trots over to me. A few minutes later, he is across the yard from me, and again I step inside. This time nothing happened. He didn't move. I step back outside and call him, and this is where I realize the correction really meant something to him (although he isn't foolproof yet). He lopes over to me, and to my right, there is that same hen that he had gone after earlier maybe 7 or 8ft away from me. When he is coming to me, he glances at the hen (no interest, only avoidance in his eyes) and then makes a half circle to the left in order to get to me without going ANYWHERE near her. He deliberately avoided her. I praised him for coming to me and then went inside and ended on success. I will continue to do this with both my dogs (I have two, and they have both chased chickens) and update if it works long term.
Should I do this 2x a day, 1x a day? Less? Let me know if I did anything too wrong! I will change it next time if I did, but my dog fully recovered from the correction and was not at all shook by it after it happened. Again, he is trained on the E-collar, so he knows what the correction is, and he is also fully aware that HE caused it, and HE can make it stop.
