I never had any trouble catching them in the havahart cage traps. And mine were fairly large raccoons. I surrounded my cages with straw bales and then covered them on top with straw, but I had a lot of raccoons so they were easy to catch, I think. Chickens are pretty smart really. We don't give them much credit but their fear makes them seem dumb when they are not. The older they are too, the more experienced and smarter. I just wish mine could talk so they could tell me what happened to the rest but that's not gonna happen.
