Get some raccoons hanging around your yard. Sooner or later - sooner I think - they will notice the chicken coop, break in (they are fiendishly adept at that), and eat ALL the chickens.
preferred raccoon attractants:
1. Marshmallows
Marshmallows make a great bait for raccoons. It's sweet, chewy, and is sure to attract the raccoons on your property! These are commonly recommended.
2. Wet Cat Food
The stinkier, the better. Raccoons love smelly, oily meats, including a nice can of wet cat food.
3. Bacon
Speaking of oily meats, bacon attracts raccoons really well.
4. Fresh Fruit
Fresh fruit is a great choice for trapping raccoons, as it has a sweet aroma that they can't resist!
5. Canned Tuna or Salmon
Just like the wet cat food, canned tuna or salmon has a strong scent that draws raccoons in.
6. A Whole Egg
Yes, you read that right. A whole, uncooked egg! Those who own chickens know this to be true. Raccoons have been known to slaughter chickens in order to get to the eggs in the coop!
7. Sweet Corn on the Cob
Sweet and fresh, corn on the cob is a great choice for baiting raccoons.
8. Sugar or Honey-Coated Veggies
Are you seeing a pattern? Raccoons have a big sweet tooth. They just can't resist a plate of sugar or honey-coated veggies.
9. Tin Foil
Raccoons are curious creatures, and a wad of tin foil can sometimes be enough to draw them in to a trap. Their curiosity will get the best of them, and they'll move in to investigate.
10. Fatty Meat
Virtually any fatty meat you can find will usually be good enough to use as bait for raccoons.
