I am not angry at your opinion. However, I am not a poultry farmer. My chickens and my ducks are my pets, love. I don't breed them, either. So, please, stop presuming you know anything about me, my pets or that they are not properly fenced in. I have done everything I possibly can to protect my them. However, if a fox, a bobcat, coyote, or anything else comes on my property that tried or actually gets one of my babies. I will kill it. There is plenty of food for them in the woods. Foxes, especially, will go after the easier to get prey. My pet chickens and ducks are inside an enclosure so, they will do whatever it takes to get in. They aren't having to chase anything down. A fox will dig, climb, jump and sometimes chew their way to get to what they want. I do have some pretty darn good roosters that will definitely defend their hens, but no amount of money will replace my babies. Once again, so glad the European rules don't apply here! Have a great evening, dear.You are free to be angry at my opinion, but killing any predator is a primitive way of protecting your poultry! A predator is doing what it was created to do, which is to kill to feed itself! You are a bad poultry farmer if you can't protect your animals by fencing your chicken coop with metal mesh. (I also mean the upper part).
If that investment is expensive for you and you don't want to completely fence your animals, then you don't meet all the requirements of the veterinary inspection for raising chickens (that's how it is here in Europe)!
You simply do not have all the conditions for safe breeding of chickens!
There are hunting societies that are responsible for pest control!
If you properly fenced your animals, and the predator still managed to kill them, the hunting company will compensate you for the damage!
See how simple it is in the civilized world?
