This will be my first fall doing the older layers. I have found the thought of it a little harder to conquer because I did get attached to them. DH does the killing and after that it is just meat and I can take it from there. We've done lots of Cornish X and mean ol' roosters. Those I had no reservations about (the roosters I was relieved to see go--and WOW do they make a good pot of soup!!)
Here's a really thorough tutorial with lots of pictures that I recommend often. They are doing a turkey, but it is the same thing.

A killing cone does make it so much easier. The bird does not struggle and the meat quality will be better as a result. You can easily make one out of extra pieces of metal flashing, a gallon bleach jug, or a traffic cone, depending on how big a bird you are working with.
Make sure you have withheld feed overnight, for at least 12 hours. This will ensure that the intestine will be mostly empty. Be careful and not knick the intestine with your knife. That's where all the yucky germs live.
It's a little gruesome, but a trick to help the plucking go a little easier is to take a pointy knife (like a fillet knife) and insert it into the dead bird's mouth, push into the brain, and give it a quarter turn. It does something to help the feather follicles to relax and it really does make the plucking easier. Proper scalding is an art... You don't want to over-cook them, it will be miserable plucking if the skin pulls loose from scalding too long. But if the feathers still seem too tight, it doesn't hurt to put them back into the pot a few seconds more. I pull on a few wing feathers while scalding to test to see if they will come out nicely.
Chilling meat quickly in ice water is very important. Getting it quickly down below 40 degrees will arrest any bacteria that may be hanging around. Some people brine them. I have never found this necessary with my Cornish X, so I don't do it. Also resting your meat for about 48 hours in the fridge will make it sooo much more tender. You need to do this to let rigor-mortis wear off before you freeze them.
Try to lay out your supplies the day before. My first time butchering, I wasted a couple hours just trying to hunt down all the things I needed!
Good luck! Enjoy your fresh, hormone and preservative free, humanely raised and processed meat! I tell ya, it tastes so much better than anything you can buy in the store--and it's worth it!
