People in the herding group say you can't herd chickens but I disagree. I have an australian shepherd who herds them. The trick is, he cant go at them like he does other live stock. he has to larn to keep his distance so they don't scatter.
he is a wonderful dog,and I love ausies. They are great family dogs, usually good tempered, and very devoted to their humans. The only trouble I have with the breed is that they can get so devoted they have to constantly come back to their master to "check" on them while working, so you have to constantly redirect them back to their job, they can be hard headed (but all herding breeds can be heard headed), and you have to be careful with them during the heat if you live in the south like I do. I shave his bely, under his legs, chest and bottom to help him stay cool
