Good to know! Luckily we have no raccoons, only hawks and coyotes.Raccoons can easily scale over any fence.. We had a coon problem a couple years ago. Couldn't figure out the point of entry until we placed a hunting camera near the run. We caught 3 coons climbing over the fence with ease. Also is was broad day light even though they are a nocturnal animal.
We bought and installed a electric pulse zapper along the bottom, middle and near the top going slightly outwards so they can't hop over the wire. It pulses evey other second giving the animal a chance to scram. Raccoons are smart, you have to out smart them and even a 12' fence is only keeping birds in not keeping certain predators out.
Take care and God Bless!
