I live on 6 square mile island with no coyotes.
Just off island coyotes will kill any chicken outside of a pen.
Here on the island, a chicken can out run a raccoon in the daytime.
But chickens must be penned up at night.
The roost cannot be too close to large screen, or the raccoons will reach through and pull the chicken's head off.
Sometimes raccoons, squirrels, rats, mice, flies, hornets, or mosquitoes come into the house.
100 years ago, with 6 sq miles of woods, the island probably supported a dozen raccoons.
But now with 20,000 people putting out dog dishes, cat dishes, garbage cans, fruit trees, and gardens... there are hundreds of raccoons here... and they are pests. Every house on our street has raccoon guards on the chimney.
