6 total... all my plymouth rocks and my favorite RIR dead at the teeth of the beloved family dog. (We don't know which one.) We think one of the kids might have opened the gate to the run. That or I didn't close it as well as I thought... they've been outside just about a week and I'm totally bowled over by the loss. We had just cleaned their pen and built them a permanent outside feeder earlier today. I've never owned chickens before this and I feel like a complete failure. I have 6 more in the brooder that I'm not feeling too positive about right now.
