I have a very small flock of chickens. I am actually working on obtaining a third party farm certification called Animal Welfare Approved. My hope is that as I set up my chickens, I can get approved by AWA. One of the items that they require is a humane method of slaughter. I've also been reading various papers published on methods of slaughter. I'm a veterinary technician by license and degree, and I've been working in veterinary medicine for about 15 years. I currently work in the animal welfare field. Right now I am working on writing the operating procedures for slaughter on my own small farm.
Here is what I've learned: Using carbon dioxide gas alone is not humane. C02 is irritating, and using it alone can give the animal a sense of suffocation. However, according to some of the poultry specialists that I have spoken with, chickens do not have receptors for Argon gas, therefore they do not get the same feeling of panic and suffocation that they would with C02 alone. You can get tanks with mixtures of Argon and C02 and use those to gas down birds. Once they are unconscious, then you can decapitate or bleed. I've read some papers that speculate that birds have a few seconds of consciousness immediately after decapitation - but I do not know if that is something that you can prove or not. According to the poultry specialists that I have talked to, the gas does not affect the quality of the meat. You can make a chamber for gassing down chickens out of materials from home depot, and the argon/C02 mixture is available through welding suppliers. It is of course more expensive than an ax.
