When we leave the gate open to the area where the flock lives mainly in fall and winter since they tend to want to eat things I have growing in the back yard. Opie will walk in and even bring a few of his girls along. lol I have even had a couple chickens and my gander come in before. My gander use to come to the back door and knock but my dog stuck her head out of the doggie door and grabbed him by the chest feathers and brought most of them inside when I heard the commotion I ran in to the kitchen and saw the feathers I just knew she had mortally wounded him thankfully he wasn't injured. I don't let the geese come into the back yard anymore They don't like the dogs and can't seem to control wanting to go after them and my largest dog does not like them at all. So they can all only be together when me or dh are all out with them. I use a long bamboo pole to keep the geese at a nice distance from the dogs.Does Opie wander in on his own?
