We've had chickens for 7 months now and our dachshund lulu has never shown any aggression towards them. She is a great mole and mouse hunter but is very submissive to our chickens. ( they run her away from her dog food bowl!) anyway we boughten daughter 3 more easter egger chicks, integrated them into the flock through the use of a playpen we built into the lot. Long story short. Each of the chicks was killed. We found the first 2 being chewed on, but thought the dog had come into the fence due to the babies flying about because older hens were pecking at them, but today lulu was actually eating our little pullet. My question is : we're these chicks vulnerable because they didn't have a momma? Lulu is usually very submissive to our hens and rooster. Would things possibly be different if chicks were hatches to a broody hen, therefore being protected? Help!
