Hello I live near a forest preserve (maybe 200 feet away crossing a street) and I've seen near my house, possums, raccoon, squirrels, chipmunks, deer, chickens, etc. I have found some bones in my back yard, and not sure what animal it belongs too. This is not the first time my wife and I have found bones in our backyard, if anything it is the third time. Any help would be appreciated, Thanks.
