Quesrion: I have a farm and in it I create oxen and chickens, but a wild animal is killing my oxen and cow, can I kill him? If so, how can I kill? Invenenated or shot down with a shot or otherwise?
It is permitted to kill an animal that is causing harm. You should however be careful to kill it in a way that doesn’t cause it unnessesary pain. You can kill it in whichever way is less costly.
