I decided to try rising chickens two years ago so I went to our local feed store and got a little flock of 6 chicks. I kept then in my garage until they were ready to be in my backyard coop and chicken run both located under a tall deck . I sometimes would let them roam free in my back yard but when there were about 4 moths old, two of them just disappear one day without a trace. I started to keep them in the run under my deck fenced up with chicken wire. About 4 months later I was woken up by my 10 year old daughter who had gone to feed then and found feathers spread all under my deck/run and all but one of my chickens were gone. The chicken wire was pushed down and seemed like a large animal had attacked then. We live in the city but our back yard has a good half acre or so wooded area so I assumed it was a raccoon or another wild animal. In April this year I decided to start over and got another 4 chicks, they grew and started laying just about a month ago, and everything was fine. Until two days ago when one of then just went missing. This Sunday morning I feed the 4 that were left one from my first flock and 3 from this year. We went out the house around 11 and when we come back I notice my neighbor's dog in my front yard but didn't think much of it as he soon run out to the street. I went inside the house and then walked out to my deck and there I saw the dog that had jumped over the fence and was in my back yard with feathers in his mouth. I went to check under my deck and two of my chickens were gone and the two remaining we're hiding inside the coop. I don't know this neighbors particularly because the are about a block and a half but knew their dog because I had found him in my front yard before but didn't make the connection. I checked his tag because he is a friendly dog and called then a left a message to let then know the situation but no response. Later on the dog came back so I walked him back to his house but they didn't answer so I left him inside and close their gate that was left open. I haven't get a call back and I'm afraid for my two chickens left
