My processing tips:
* The night before slaughter, I gather up the cockerels I want from their roosts and put them in a little brooder coop we have, with water only. They sleep in peace and comfort, and it's easy to catch them up at slaughter time with little fuss. I can take my time feeding the flock and tending other animals, heat up the scalding pot, have breakfast, and start processing when I'm good and ready.
* I talk to my birds and pet them as I carry them to the killing cones. I remind myself they would not exist but for me incubating their eggs and raising them, and that their purpose in life is to nourish my family. I tell them how thankful I am for their lives, and I say a prayer of thanks as well. Then I get it over with as quickly as possible. It's never easy. It gets more familiar each time, but I still dread it.
* I like to use a PVC cutter or a razor-sharp knife, and the killing cone. It's error-free, done in an instant, bird doesn't flop all over the yard, mess is contained, and it's as humane a way as I can find. Everyone has different methods; this is the one that works best for me.
* I keep scalding water 141-143 degrees F, never higher than 145. Takes a few seconds longer to scald, but plucking is smoother and easier, and that yellowish outer layer of skin rubs off so easily without tearing or cooking the skin.
* I use a scrap of cloth or paper towel to grip the crop and pull it out when processing. Makes a slippery job much easier.
* Offal and feathers, etc. gets buried in the garden for fertilizer. No waste.
* This year, I've been putting the cleaned and butchered birds in a tub in the refrigerator for three days, to "rest". By this time, the joints are limber and rigor mortis has passed. Then I put them in a tub with brine (1 cup kosher salt to 1 gallon water) and weigh them down under the water. Overnight or 8-12 hours, no more. Drain, rinse, let them sit in clean cold water for another hour or so, drain and rinse again. Then bag (I use poultry shrink bags - love 'em), weigh, label, and freeze. OMG so TENDER, juicy, and flavorful!!!
