we have chickens,and the dogs killed them when they got into the outdoor fenced in grazing area for them. They didn't eat them, just killed. My dh got six more a couple weeks later ,and no longer lets them out to graze, he even took the fence down. I know if you train the dogs, long line, call them off when they chase, they should know not to attack. But we weren't so lucky, and it happened on Mothers day last year when I was making my rounds to my (two + inlaw) mothers. I haven't worked the dogs on this yet this spring, but would love for the chix to have free range.Am interested in other training methods, E-collar will be one suggestion, I am sure.
