Check ground edges of coop for tightness. Raccoons may dig under fencing or enlarge existing spaces. Coop doors should be close fitting and sturdy. Beware of plywood doors which may have substantial warp at corners. Simple door fasteners, such as plain hooks, should be replaced with more sophisticated devices such as safety hooks or locking hasps.
Raccoons can manipulate and open elementary door latches.
Smaller size wire can be installed near roosting areas. Birds housed in wire or plastic cages should be kept within the confines of raccoon-proof buildings at night. An alternative solution is to hang or suspend cages from ceiling at least 4 feet above the floor and 5 feet away from walls. The use of a watch dog may prove advantageous in preventing damage in some situations. However, this is not recommended due to the fact that raccoons can be extremely vicious.
