I live in the mountains of Colorado, deep in the heart of bear country. Now I have never had any problems with bears but here are a few things we have done to help prevent bears.
- We have 3 large dogs that are outside at all hours. They bark at anything that sounds or smells fishy. We still have elk and deer who come on the property however I have never (to my knowledge) had bear, mountain lion or the bobcats on my property.
- We installed an electric fence, so if my dogs do not deter a bear the fence will. Bears hate to be shocked. Our first fence is around the perimeter of my home, We have our land sectioned so this is not our entire property but just a smaller section. Our second electric fence is a portable solar operated electric fence we purchased from Premier fencing. We love it! My dogs will not even go near it. This fence surrounds our chicken coop, rabbit hutch, compost and bees all that would seem an open snack bar to the bear.
- A trash dumpster is located in a completely separate area of the property. Bear love trash if they cannot find food.
If you experience problems with bears it is likely that fellow neighbors are too, I would call the wildlife office near you, make a complaint and if they have enough complaints or a bear is attacking wildlife or damaging your property they will work with you and neighbors to remove the bear to a safer environment for the bear. Bears will come back to the same place, especially if you keep making the food, aka your chickens available to it.
I recommend an electric fence, spike boards also help (bears do not like to step or prickly things), if you compost remember not to compost meat or anything like cantaloupe, and of course Dogs, Dogs, Dogs!
I hope your chicken is okay, give it plenty of TLC, keep its wounds clean and make sure it is eating.
Good luck with your bears, if you want a large number of links (I have read a lot on the subject) I can send you some more information.
