My neighbors and I got day old chicks together in January. They have (had) 5 and I have 9. We live on an acre+ each and are good friends. We have two dogs (corgi mix muts) one is super submissive and would not hurt a fly, the other (litter mates) is dominant and always doing Alpha things. Our neighbor has a wonderful blue heeler who is wonderful with their chicks. Two nights ago we transitioned our chicks to the outdoor coop in the backyard. The dogs are outdoor dogs and they will share the backyard. I've spent many hours the last two days sitting with the alpha dog by the coop correcting her and letting her know to leave them alone. That said, I would never leave them out in the yard, they were in a protected run. The incident: Our neighbor was home early from work and decided to let his chicks run free in the yard for a bit. He went inside to get a drink and when he came back out, my dogs had dug a hole under our fence gate and run over into their shed and had the chicks cornered. They took one and killed it. It was in my backyard a few minutes later. My neighbor went looking for it and there it was... in MY backyard with my dogs. I feel so terrible. My neighbor is being so wonderful and nice about it, but its awful. What can I do about this dog? Can it be trained? Is there hope? Is my backyard going to be forever a war zone? I plan to take measures to ensure the backyard will contain them to keep the neighbor chicks from sure death, but what about mine? Was I silly to think that we could eventually have free ranging hens and pups blissfully keeping watch in the same backyard? I don't know what to do. Help.
