I had a neighbor's dog (let's call it Satan) get into my backyard and harass my chickens. Satan had a mouthful of my Lavender chicken's feather's in it's mouth, Lavie went into my house when I went out to get Satan and she appears to be okay. I've got 3 chickens missing. I know one of them is fine as I saw her. The others I think went over my fence to some wooded area and I don't see them. 2 of my 5 are back in the coop and I don't think they're leaving. I do have it open as the others need to come back. How late would they stay out if they're going to come back? I don't want to leave the coop open all night, but I don't want them to come back and have the coop door closed.
