I mean, do your due diligence, But usually if you are defending your property, including pets and livestock, there is an exception. The guidelines and ins and outs of this are going to change and vary from state to state and even county to county in some cases, so do a smidge of research or contact your local authorities for clarification. beyond that I would suggest picking up the tools and skill to dispatch the animal yourself, as you may have to take it while its in the act. (Here being on my property is reason enough so long as they are not protected) I do not relish the idea of taking life, even killing insects inside my home, I can feel the stain it leaves on my soul. I also say this having gone to war (I wasn't directly in combat as I was a rear echelon MOS) But I've saved some of my baby chicks from rats, I've deterred arial predators (and my dogs) with loud noises (Where I am at, putting a bullet in the ground does not count as a negligent discharge as I have the property requirements to shoot recreationally in my backyard so long as I am shooting in a safe direction.) All I'm trying to say, though, is having the proper tools, education , and developed skills may help you defend your flock in the even the wretched thing returns. If you have any questions, feel free to contact me in the DMS.
