So I'm not sure how but my chickens got out of the coop and into my main yard where my dog was. They have they own run but I hadn't gone out the open the run hatch yet when I heard a ruckus. I would assume the dog heard the morning food ruckus and went to check some how bumping the latch and letting the chickens free. Fortunately she only harassed them a bit and I was able to round 5 of the 6. But the other is still MIA. I can only assume she hopped the fence, her wings are clipped but I imagine with enough reason she could have easily hopped over the wall at one end where the hill on the side of my yard come within 3 feet of the top of the fence. Unfortunately, we have asked all the neighbors and checked the area on the other side of the wall but we have large fields near us that are very over grown with black berry brush and i'm afraid even if we find her we won't be able to get her back. Does anyone have any suggestions other then counting her as a loss?
