@bamadude I forgot I was supposed to share this link with you:

It start's with the deed itself. I've been using hedge shears, which worked great the first time, breaking the neck and cutting the jugular on both sides, but the last time I used them, it only broke the neck, so I would maybe not recommend this method, unless you place the shears so that the feathers won't block the cutting edge. The scalpel is better, but requires you to find the spot to cut at pretty precisely.
The noose to hang the chicken from it's feet from is a great technique, the chicken becomes pretty disoriented upside down, and I'd say this minimizes struggling and suffering as long as you don't hang it for a prolonged time. I've liked using the trash bag to collect the blood, and to calm the chicken down.
Washing the chicken with a bit of soap works well, it lessens the stench when you scald it later. I first wet the bird a bit, then rub in some soap (I use a pine based soap) and rinse it properly, cleaning away the worst poop. Wetting the feathers prior to scalding will make the scalding work better too, as the hot water will heat the water already in the feathers.
The scalding works really well the way it's described in the link too. We've only done birds individually, so we haven't had to worry about the water cooling down when doing several birds. With one bird, I use a 8 liter (2 gallon) bucket, in which I pour about 4 liters (1 gallon) of boiling water, and then I top it up with cold water until it's 65C/150F. Then I hold the bird in it for about a minute (when I say 'I' I actually mean Karin, I've outsourced this to her), and then the bird can be plucked. We just hang the bird back in the noose we used for hanging it from during the killing (still from it's feet), and pluck the feathers into the same trash bag that we drained the bird into, as we don't want the dogs to dig up the spot where we do this.
