Hi Carolyn
In my experience the killing is the hard part. I did lots and lots of research before I attempted it. I had seen a wonderful you tube video of an American lady resting it in her lap and stroking it until it relaxed and then cutting the carotid artery and bleeding it whilst still stroking it. Decided that was a really caring way to do it, but was then informed that it's not legal to bleed them before stunning them here in the UK so I ended up using a broom handle and would strongly recommend that as the best layman's option. Hold upside down by the feet. place broom shank over neck, stand on the broom shank and pull upwards and backwards sharply. If you pull too hard the head becomes detached, but much better to pull too hard than not hard enough and you need the head off anyway at some point.
I've tried removing the head with an axe afterwards and failed to make a clean job first time, so I'm pleased I didn't go with that means of killing. I'd never manage a clean strike with a live bird if I can't manage it with a dead one and the trauma of getting it wrong would stress me to death!
Anyway, once it's dead, Hang it and bleed it (cut the carotid artery) and then pluck and eviscerate the carcass. There are some really good you tube videos that show you how to do this. It took me quite a while but I was really pleased with the result. If you dip them before plucking, be prepared for it to smell. I made the big mistake of filling a trug with hot water in the house and then couldn't lift it outside, so I dipped it there in the kitchen.... very bad idea!! I probably wouldn't dip it to pluck it next time. We dry plucked when I was a child and I found that the feathers stuck to my hands when they were wet and it wasn't appreciably easier to pluck having been dipped, but maybe I didn't get the temperature right.
Anyway, good luck with it. I have 9 more waiting for me to psych myself up to the job.... it's the killing part that's deterring me.
Do be prepared for them to flap a lot after they have been killed and keep a hold of their feet until they stop.... it can be 30 s to a minute.... feels like a lifetime!.... sorry, I'm not selling this very well
I do feel quite strongly that anyone who eats chicken should experience this though.
Anyway, once you have processed it, leave it to rest in the fridge for a couple of days. The best way to cook the carcass is in the slow cooker unless they are only 10-12 weeks old but unless they are proper meat birds you will need to keep them longer than that to be big enough to be worthwhile processing.
I hope that gives you some insight.
Good luck with it
Barbara
