Here! Here! Sometimes a ‘humane act of kindness’ towards such vermin can come back to bite ye in the buttocks! Not having any chickens or such that if you happen to see a random rat outside would be of any concern other than said vermin getting inside your home, then ignoring the rodent would be adequate. However, having animals and feed of these animals; BOTH that will attract mice and rats is a different story. They carry deseases and can make you or your pets and livestock sick simply by coming into contact with their excrements. So it’s the responsibility of us chicken owners to see to it that these types of animals are swiftly and successfully dealt with. Or else they will continue to be an issue. Just last night I had to terminate a possum that’s been harassing our cat on the back porch. She’s old. 16 years old, and I don’t want any other wild animal attacking her and possibly killing her or giving her rabies. That’s the responsibility I have as a pet owner. And making sure rats do not cause issues with your chickens and get into your house due to having chickens and their feed present is our responsibility as chicken owners. With that being said, sometimes we have to put the well-being of our animals above the humanity of trying to get rid of such vermin.
