That would all be well and good but I fear that you are overlooking an important part of Raccoon behavior.
Like the bison, Raccoons live in large groups. Coons are more like Icebergs than an iceberg, 90% of the coons in your location (or in anyone else's location for that matter) is out of sight. In wild life management there is a term called "Carrying Capacity."
An animal species will reproduce or colonize an area until the available food is consumed and all the good nesting locations are occupied. Removing an individual coon makes room in the environment for another coon but it also lessens completion from the remaining coons for natural raccoon food. Besides coons are a serious danger of harboring dangerous parasites and serious diseases.
Here is a small example of the type of coon population that a little food will bring to your chicken coop.
They like Cheetos too.
Most of this is incorrect, and that video shows an atypical gaze, that probably feeds exclusively by the generosity of humans, and for many generations. Males live in small groups of about 4. Females live in similar groups with their kits.
The raccoons have a cat food buffet and warm place to sleep right next door, as it has been for years, and we're not overrun, because that's not how it works. This raccoon probably wandered over here because the frost last week and heavy rain killed the bugs and dropped the nuts early, so lower fat wasn't cutting it. We're only about 6-8 weeks out from their low activity here, so that's how long I'd be offering them fast trimmings and fish skins if I did try it as a desperate measure. That would hardly create a stir in the local population or make them dependent. Their diets aren't high in chicken heads, but they probably need the fat. But that's why I wanted to be sure they aren't sport killers.
I came here to ask about the gadgets for keeping them from the coop because I KNOW the two mentioned methods are only bandaid effective!
As for this harbinger of disease, well, my water is filtered, my mammal pets are rabies vaccinated,and we are hand washers. Roundworm from raccoon is very rare. Lepto and salmonella can be avoided with basic sanitation. Giardia, well, we aren't drinking from our creek. I'm not at all worried. These things don't feel like a significant threat (it's actually my field), because numbers tell me my neighbors and even you are a bigger threat to my health than a raccoon.
My chickens are locked up at night, but I may give a strobe gizmo a go (I know that would scare the dickens out of me if it was hooked to my fridge while I was looking for a midnight snack! ). Thanks for the idea, mutt farm!
