Lost over half my flock. I re did the coop. Put wood along the bottom of the run, put a front on the coop, secured it really well. My shepherd actually ran into it running and it held up. Well the night before last, apparently something broke in. Got the twins (barred rocks) got the producing rir, and one of my game birds is missing. I found my other game bird in a tree and the roo was hunkered in next to my shed. Only known survivors. Now they aren't interested in eating, and the game bird is just pacing the fence line :'( I also haven't heard the roo crow this morning Worst part is, I think it was my shepherd. She showed no interest in the chickens when I brought her back here. The pup is kenneled over night. So the shepherd had full run of the yard. Neighbors said that they heard "dogs" attacking the chickens. I only have 1 that isn't kenneled. But my buddy down the street has 2 (mom and son) that are escape artists. The son was hanging out in my yard a couple weeks ago while I was doing chores. So he knows that they are back here. My back fence is only 4' tall and the dogs have been known to climb 8' fences. I'm so heart broken. I'm sick.
