I, personally could never drown an animal. I have a morbid fear of drowning, myself. Just the idea of a critter being held underwater, struggling to breathe air, only getting water in the lungs, panic, slowly dieing. And I've read here that ether in the concentrations used to kill, cause pain in the animal as it inhales that first lungful of straight ether. Just because the lid is on,and you don't see the suffering, doesn't mean it didn't suffer. To me (and this is a personal opinion, only), a sharp knife, or machete, and instant removal of the head induces less suffering. But each of us has to choose that which we are ABLE to do. Do whatever your concience tells YOU is right, and you are comfortable with. But rest assured, no matter which method you use, it won't be easy, and you will be saddened. But, if in your mind, you are sure it is a neccesity, you will learn to live with it. Just do it with compassion for the animal, and you have made the right choice. We do use our chickens for meat as well as eggs. Every chicken we slaughter, we thank for the gift of food they provide for us. The last thing before the machete swings is 'thank you for this gift of food you are about to provide'.
