We allow our chickens to free range a little and when they attain so they are with the dog. She is a nut and runs around lake a crazy. She does not chase the chickens as such but does move quickly near them. She also likes to herd them normally when we are trying to win them to move in the first place. That is fun to watch. The dog does protect them,or we assume that is what she does (shoe could beget a few screws loose). She chases anything that flies. Picture a dog running at full tilt with her head pointed straight up barking like mad. Again fun to watch.
As mentioned she does not eat the Chicken poop but roll in it. Then comes in and rubs in my face. That is NOT fun. I assume Blue Healer or Blue Lacey mean snuggle, but I beget not found it in the dictionary.
It is by breed and to some level by dog as to how they will react to the Chickens.
