I'm so sorry about your pullet Dawn. I hope the neighbors will keep the dog up after that. I know how aggrevating it is to put up with people like that.
My neighbors pit bull actually came to our yard today too. He's been there a couple time in the past, but not for a while, and both times the chickens happened to be up.......he breaks his chains and clasps.
This time the chickens were out, but I heard my dogs acting up and figured something was in the front yard. I got him just before he got around the corner. He rolled over and acted cute long enough for me to grab a section of one of those cable pulley system things you use for dogs, so they can run the length of the yard (can't recall what those are called right now). I just happened to take one down recently. The dog that was on it died a couple of years ago (she was about 16, and she was a digger so I had to keep her on it), but I couldn't bare to take it down then, and it happened to be laying in the yard, so I unhooked the piece that you hook the dog to and hooked it to his collar and walked him home. Now, how lucky was that that I had that cable thing laying right there!?! Seriously! If he'd have gone about 4 or 5 more feet he'd have seen around the corner of the fence and seen the chickens in the back yard. Too close for comfort. I went over and hooked the other end of the cable to his kinked up chain and yelled for the owner. He was in the backyard working on his dog pen. I didn't even know they'd made him one, but evidently it's not keeping him in any better than the chains have been! I guess I won't be able to let the chickens out now. I just hate that! I have one nice 6 foot run, but the chickens on the other side of the barn only have a 4 foot run, and they can fly over if they want to. I don't know what I'm going to do.
