This is a sign which I designed to warn people (and potential intruders) that there are raptors/chickens on the hunt on our premises... ;-)
You can either print it in one color and paint it afterwards or you can also easily print it in two colors by spliting it up in your slicer software in a height of 5mm, if it supports doing so. This video explains how it can be done in SIMPLIFY3D: https://www.youtube.com/watch?v=KV2AjyowXX4&t=1035s
After you have printed it, you can attach it to a fence by putting 4 small zipties or wires through the holes on the backside.
It would be nice if you would post a photo of your make, when you are finished :)

For 2 color print, split the part in your slicer software at 5mm height.
