I presently have one rooster and two hens, but am expecting six more hens soon. My chickens free range during the day and go into their coop at night. I have five dogs, all rescues, who pay no attention to the chicks. I have just rescued two starving puppies, about 4-5 months old. As soon as they saw the chickens they made a dash for them, each puppy caught one of the chickens and had begun pulling feathers out by the time I was able to get to them. Poor rooster has no tail feathers left. I'm now keeping the chickens in their pen during the day. I found this forum to get ideas on how to train the puppies to leave the chickens alone. If I can't train them, the only option will be to take them to a shelter, which I don't want to do. Many thanks for all the good suggestions that I have read. I'll start working with them right away.
