We went away for the weekend & couldn't get anyone to close the coop for us. I left plenty of food & water, more than usual (3 full feeders) I only have 5 chickens so not a bunch needed. I lost a chicken last week to a coon so just before leaving I ran an electric wire around the top of the fence. It must not have worked. We came back today to find only the rooster was still alive. He had flown the coop & was loose in the woods. The rest were eaten or headless. This won't happen again.
