We have two Irish Setters, and two Black Labs. None of them had been around Chickens growing up. The setters are natural hunters, and of course this was a problem. I had raised Buff's, and one of the Setters got ahold of one. Killed it, and by the time I reached them.. the Labs were in on the situation. I wanted to beat them all!.. Non the less, I brought each dog, one by one.. back to my now dead baby.. I made each lay, (they knew how ticked I was), but each laid on their backs, feet up in the air.. . I pushed my bird over towards them, they wanted no part of it. I then brought one of my other birds over, and let the bird down.. The labs got the message very quickly, the setters, thought I was bringing another for dinner. As soon as they would show interest, I would tap them with my fingers, kinda like a quick motion, so their attention was back on me. I only had to do this that day.. .. now they understand that the birds are part of the pack.. My setters still kill wild bunnies, but will not even look funny at a chicken.. Thats what worked for me.. I'll see if I can find something on youtube that explains..
