Tonight my entire flock was slaughtered by my family's Rottweiler. They were being temporarily(we just moved and the birds hadn't even been here 2 days) housed in an old cinder block chicken coop type thing until my father could make them a permanent coop outside of the yard(the yard has wire for shock collars) I was already planning on getting chicks this next year :/ unfortunately this was the third( could have been forth) flock in 3 years killed by dogs. This flock was my flock instead of my family's. I just so tired of worrying if any of the chickens I get will make it a year. Is there anything I could try to get her not to kill? We have 2 other dogs that would probably need it too. But the Rottweiler is around 7 years old and has a skull about as thick as a building.
