I have a Blue Heeler that watches my chickens.Those of you that have heelers know how they are. Cody picked up on my signs,THAT YOU BETTER LOOK THE OTHER WAY,When it comes to my chickens. He has gotten to the point where he will not even let people he knows around them.He knows how much I love them. He was the same way with my kids. We all know dogs are teritorial,but they see how much you love your birds & they will too. Some dogs ofcourse can not resist. Pet That good boy on his head for me!
