RACCOON BATTLE CONTINUES

I have lost every battle I have had with raccoons, but I was told that if I used a chain to hold my bird feeder that the raccoons wouldn't walk down a chain, and if they did I was to add barbs of wire in the links to stop them. Tonight I hung my bird feeder on a length of chain and will see if they put it on the ground like they did recently. The first time I put the feeder up they unscrewed it and dropped it on the ground. I put it back screwed tight and a couple of nights later they had it on the ground and bent. It is a metal with glass panels and now a little bent. I have been bringing it in at night and that works but is aggravating. We will see.
