Ive never canned chicken meat, just double wrap it in freezer paper and stick it in the freezer. How do you plan to eat it, dumplings, soup, stew, casserole, maybe dry it a bit and enchiladas or tacos? You should have plenty of options.
Ill probably smear it with basil, oregano, maybe parsley and/or thyme, put it in a covered roasting pan with a bit of water, and cook it at 250 for 3-1/2 to 4 hours. Its a 6 month old cockerel, way to old for frying.
I got the electric netting because of people dropping dogs off out here. Ill not rant too much about that but it is FREE to drop them off at the pound.
Its 4 feet high from Premier, 165 feet long. I have it attached to my permanent coop/run so I have some limits how I can set it up, either short and wide or long and skinny. During the summer I dont have to move it because of the grass. The grass does not disappear. But in the winter when the grass is not growing, I move it around to try to keep it from becoming bare ground. When the grass starts to grow in the spring I leave them locked in the run a couple of weeks to give the grass time to get some growth. They love that tender stuff as it is just sprouting.
One big problem with it is that it will ground out if the grass or weeds get very high in it and it rains. When the grass is growing well you have to move it and mow at least every two weeks. Thats a pain. After the grass is well established and Im satisfied they wont destroy it, I spray round-up around the perimeter to stop the grass and weeds from growing up and grounding it out. That saves me many hours over the summer.
Its only 4 feet tall. They can fly over it if they want to, but they dont. The only times I have problems with it is when I have young cockerels in there. I think they get in their fights and the loser gets caught against the fence. When he goes vertical to get away, he winds up across the fence and doesnt know to fly back in. When that happens they always roost on their grow-out coop, so I wait until after dark and catch them.
I find that if I make it sort of long and skinny more get out. Its just easier for them to get trapped against the fence or in a corner. How you configure it does make a difference.
We called the Sherriff , gathered the fallen troops from the battle field, then a month later we got a small claims court judgement for triple damages. 
DH was delighted to off the 4 roosters because they crowed all the time and were so loud.
