I had posted a device that signals when there is movement (the same little sounds you hear when walking into a retail store). It is a two piece unit you can pick up at any hardware store for cheap. You can set the little box in a place in front of your coop and place the other device that signals when someone/something walks by in your house. Then ya'll could sneak back outside and take care of business! It works, it's cheap and you don't need to sit up all night hiding in a bush.
