The slaughter has begun

I hope it's the end! This morning we discovered 10 of our 37 chickens were missing. All that was left was a few feathers on the ground outside of one tractor and the mangled remains of one of the cochins under the apple tree. Wouldn't you know they didn't steal any of the roosters in the less well secure tractor. It looks like the local raccoons can open the sliding locks we have. So now we need something more complicated before nightfall. I am so angry for those poor birds. The raccoons opened the back door and just reached in and grabbed them while sleeping in the nest boxes I assume. I wonder how much raccoon traps cost?
