We have a 14 week old small breed puppy that has never once messed with the chickens. If anything, he avoids them. My chickens free range, so he is around them all the time, and we have had him for a month. One of my chickens suddenly today started being very aggressive with him, for seemingly no reason. He will be peacefully walking on the other side of the yard from her, and she will charge at him, and the chase him, all the while pecking at him and clawing at him like fighting chickens do, when they hop up and fight with their feet. kwim?? She does it EVERY time I let him outside, even if I am standing right there. Said chicken has never been aggressive with me or anyone else in my family. WTH?? How do I get her to stop? I don't want my puppy to become afraid of going outside.
