Of course a vet isn't always an option to everyone, nor is it the chosen option for someone who professionally humanely dispatch an animal in a more effective and potentially less painful way.A lot of times a Vet is not an option - period.
Just for **giggles** a couple of years ago, I called the vet clinics in my area, totalling to around 45 Licensed vets between the clinics. I asked if they could run a fecal float or if they treated poultry. I got laughed at, I got hung up on. Not ONE (1!) vet clinic would see poultry, this included *Avian* vets too.
So, it may shock and disgust you, but sometimes you have to pull up your Big Boy Britches or Big Girl Panties and get on with the task at hand.
For me, my face is usually the first human face that my hens and roosters see. My face is the last human face they will see too. They are used to me, they know me. Why on earth would I want to box them up, drive them to a stranger and put them through a terror they never have experienced before when I can, with love and compassion take care of them myself? It's not about money. Perhaps you're o.k. with strangers putting your much loved animals through that, but I'm not.
My argument is that the individuals seeking help here are not experts in humanely dispatching, and are being adviced to attempt this as a standard practice over seeking vetinary assistance. The amount of pain people are causing as a result of this absolutely shocks me. I am reading countless posts where people are maiming their animals to save a few bucks.
Do not experiment euthanasia on your pets. Do not use it as a default option, if better is available. If in doubt, find a vet. Who would even argue that?
