my 2 dogs free range unsupervised with my bantam chickens and ducks without any trouble and have for a couple years now, but I agree that it is dog's nature and I could not blame my dog if it were to eat one of them. I am just lucky and it would be my fault if that happened for trusting them alone with them, I do trust and believe my dogs would not harm them... but you never know and the responsibilty is mine not the dog's. I would be mad, but wouldn't take it out on the dog other than a reprimand "bad dog" and "no" and maybe a time out.
