We lost 5 of our 7 chickens to a couple of domestic dogs on the loose in our semi-rural area. We live on 2+ acres and are surrounded by other similar sized lots with a big open national forest lot to our south. We had been allowing our flock to really FREE-range over our lot and into my neighbors's and part of the forest. Figuring the daylight hours were "safe" and the rooster would help protect the girls and that they had plenty of sheltering options... this seemed like a way to have truly happy chickens (and they WERE...). Sunday afternoon changed all that. One hen must have been completely off by herself as she seems clueless on the destruction, the other had many of her back feathers ripped out and a couple minor sores -- both are thriving We're keeping them in the coop [hardware "cloth" barrier should protect from digging predators] -- no more roaming the land until we can figure out options. Here's a tribute video I put together to honor our lost dear ones.
