Yesterday I found a nest that one of the stupid chickens had created outside the fence. All the eggs had been cracked open and licked clean. There was also plenty of raccoon scat present. So, I dug out my second solar fencer and put some juice back into the fence around the chickens. We have had exceptional luck with the electric poultry fencing we use. If the birds are smart enough to stay inside the fence and go into their coop at night, they have no problems. The dumb ones don't last long.
Today our friend Jack-of-all-thumbs posted his recent adventures with chicken predators
I sent him the following solution which I have used in various locations with great success.
If you make the mesh on the ground about 18 inches larger than the upper step all the way around then any four legged creature trying to get in has to stand on it and touch the hot upper step. The shock seems to keep most critters away. Chickens, being two legged, will hop from the ground to the step and not get shocked. Simple, but it works pretty well.
