Hi everyone. I recently got 10 hens and 1 rooster. They have been free range for the past week and have been doing fine. Today my husband and I both went to work and when we came home all chickens were missing but 3 hens. They were in their pen today. The only evidence of something happening is mud and dog hair on the coop with pen wire pushed over. The neighbor told my husband this past weekend that his dog kills chickens. I did not find any bodies or anything, just dog hair on my coop. What do you think happened? Oh and it 100% belonged to neighbors dog as it matches her fur.
