Nope, you had it right. That is exactly what I was saying.
Accidental escapees notwithstanding, if you love your animals keep them confined to your house and your property.
This is untrue and I have a hard time that somewhere in your heart you don't know that. As someone who had three feral cats show up the neighbourhood, two who were pregnant, and who adopted them all due to lack of space in the local shelters (for a total of 3+4+7!) cats, they were too feral, but in the process of being tamed, for a half year, and in the process of being training to not go outside at all for another year. I can tell you I dearly love every single one of those cats who are *now* securely inside and spaid/neutered, but who I prayed for every time they left our yard. Did I lose some to threats? Yes, two died as kittens to roaming rottweilers (who came on our property-- would it have been fair to kill those, too?), two died to cars, and two disappeared. Did I grieve horribly every time this happened? Yes, I did. If someone killed any of them, they caused me months of horrible grieving and poor mental health, and I still sigh and wonder what happened to my Mars and grieve over my Nova getting hit.
You raise chickens. These creatures humans have domesticated and bred to be the ultimate prey animals. We also domesticated cats to take care of small nuisance animals. Don't make the individual pay for a human or humanity's sins.
And talk to your neighbours and try to figure out a solution. We live in 2020, not the bronze age. There's no reason for such violence, especially if you let your *prey animals* roam around unguarded.
