I did not have a raccoon/possum bale on either bird houses I had just one metal baffle on the chickadee house But I think the possum used a nearby tree to get on the house thus dropping down and avoiding the baffle. I am devastated. I’ve had these two houses up for years Even replaced the bluebird house with a new house last year. I live in the wetlands off of Highway 98 near Gulf Breeze Florida. This has never happened before in my past 8 years of living here. I may take down the houses
