I agree with silky4. Justjoenhix...I appreciate what you’re saying but witnessing an actual possum mitigating your chickens tends to dispel your confidence in possums never kill chickens. In fact, in our neck of the woods in La, it’s extremely common for them to kill, mot often severing their heads, and leaving them. We’ve seen it with our own eyes and we aren’t out to punish these possums. In fact, they are usually found eating with our cats, even before dusk, especially very young ones that don’t quite know they are typically nocturnal yet. We don’t get aggressive with our deterring methods until we have proof they are the aggressors. We are by nature lovers of all types of animals and understand this is their nature, at least here, but they have plenty other means to feed themselves and no reason to kill our chickens and leave them for us to find the next day. We have possums who even take advantage of small kittens who can’t protect themselves yet. They’ve wiped out an entire new litter before we could get outside to stop it. I’m willing to try any non-lethal methods and I know radios keep the coons at bay, so seems logical the possums might stay away as well. This is a regular Noah’s ark here but rarely do animals in captivity OR in a habitat behave the same as if they were in the wild, fending for themselves. In my opinion, it’s also not wise to apply the same personal knowledge to all species of opossums and/or different geographical locations. I always say...firsthand knowledge and eyewitness experiences trump what the books say are the “norms”.
