Miss Red, I'm so sorry for the losses, its always hard to take!! I have found my barn cats attempting to get into the stalls I use for brooders but then they'd have no way out and yes, I'd HUMANELY SHOOT THEM AS WELL. For someone who said to take them to the shelter and have them humanely euthanized? Shooting accurately IS humane. Have you ever held a healthy dog or cat that is being euthanized with drugs? They cry out as the stuff goes in the vein, they struggle, they sometimes scream out. I do not consider that humane, a well-placed bullet is the most humane of all.
If you saw one of your cats running off with a half eaten chick, its very possible that they did cause the carnage. I have seen cats take on and kill, a 2.5 lb., rat for goodness sake, a small, fluttering chick is nothing for a stealthy hunting cat to take. If it were dogs there may not be anything left, since they usually gulp the chicks down. Cats if they cannot swallow, will surgically gnaw their victims in half, eating the best part and leave the worst part (back half).
