Ok, let's stop all the misinformation. The bottom line is this- If you are a BYC'r your chickens have no value at all. I know, I know Buffy was a lifelong friend and companion but there are laws. If no laws are broken then there is no crime and thus not punishable in our wonderful legal system.
That being said... I raise hundreds of chickens for eggs. I have a business license and am state inspected. This puts my chickens under livestock laws (which may vary from state to state). In my state each chicken will lay eggs equivelent to $5000.00 dollars over their productive laying lifetime. If I have a previous greivance against an irresponsible "pet parent" it doubles. You know, like hitting the double bumper playing pinball. That's $10,000 per chicken for those of you still struggling with the laces of your shoes. ;-) That being said, I have notified, by certified mail, every property owner in a five mile radius of my free range operation that if my livestock is harmed or harrased by their untutored pets, they will recieve, for their irresponsibility: - Photos and an HD video of their furry human companion killing less than or equal to 10 of my money makers, a .22LR caliber of love round to respective brain pan and a carcass of same on there doorstep along with a summons to appear. For those of you still struggling with shoe laces, thats $50k minus legal expenses and .10 cents for a .22LR. I love animals, but I hate irresponsible pet owners. If I could legally shoot them instead of their pets I would. If you think retiring and raising chickens isn't lucrative, you should move to a state where firearm and livestock rules favor the prepared. ;-)
Just a reminder, dogs unlike ANY predator, will kill many chickens, a predator will take one. And in my case, pet parents can be sued for losses and spot won't being playing fetch any time soon, unless of course you are a Stephen King fan or are a very connected lawyer. Either way the problem will be resolved, and at least as far as precedent has established, in my favor.
Check your local laws or for you google-kin "livestock laws [state you live in]" get a business license or have the chick provider on speed dial.
And for those of you who are aspiring lawyers or Internet Know-it-alls, in my state livestock laws are on my side, and where I live discharging a firearm is not illegal, nor is protecting livestock on PRIVATE PROPERTY. Do your research, and not on an Internet forum before you undertake any aforementioned action. This means consulting with a county official, the sherrif or a lawyer. Better yet, get it in writing and witnessed because, hey, polititions and lawyers... enough said.
OP, Sorry for your loss. :-(
