Just wanted to put out a huge 'thank you' to all who've provided advice in keeping chickens safe. I say this because three of our neighbors have lost chickens recently to racoons. One lost 20. The other lost all but one (don't know how many she had overall) and the third lost 11 out of the 17 they had. In two instances, racoons were killed inside the pen or coop. I realize they're only livestock but we've become so attached to ours that we couldn't imagine even one of them dying due to negligence. We not only close our pop door every night, I'm now considering drilling holes from the outside of the coop, through the wall studs and into the side of the door so I can slide a 1/4" rod through as a deadbolt. It would only have to be about three feet long to reach. The only other way in would be the windows and they're screened with hardware cloth. Thanks again.
