I am very new to chickens, will get my day old chicks in a couple of weeks. I have already a safe place for them to grow where my dogs cannot get to them, and the pen they will go into when big enough is secure also, but I am worried about determined (wiener) dog. We have several dogs, that have never seen a chicken, even though the pens seem secure to me I am concerned that they could find a way to get in when I am at work. Has anyone had any experience introducing dogs to the chickens? All my dogs are friendly w/ each other, other dogs, and cats.
