I looked on youtube for information how to kill animals with Carbon Dioxide.
here's one video: chickens in a C02 bucket:This video shows chickens placed into a bucket which is
then filled with carbon dioxide gas. They do this twice with two different
chickens. Once the tap is opened to let in the C02 gas into bucket, the
chickens immediately react by pecking or kicking the inside of the bucket.
It's not a peaceful death for these chickens, at least, not for the chickens
featured in this video... They panic and one of the chickens (the second)
nearly knocks the bucket over with it's frantic panicking.
I dont think this is a humane way of killing chickens.
It's just less UN-pleasant for the owner of the chickens
(because they can't see the suffering of the chickens ... and there's no blood)
https://www.youtube.com/watch?v=CEy97j3vNoghere's a second video: Rodents and Carbon Dioxide The second video shows rodents being killed with carbon dioxide gas.
This looks altogether more peaceful. The mice stop moving around
and start panting heavily... but they stop moving. The chap recording
the video explains that when they start 'kicking'.. it means they're
dying or they are dead. The mice in this video dont kick.. so the video
shows an "attempted" killing of the rodents... It's not clear that they die.
https://www.youtube.com/watch?v=1De8sW-f_BsThe way this chap makes C02 is interesting.. and simple.
He mixes vinegar and baking soda to generate carbon dioxide.
This is simple, but needlessly expensive.
A cheaper and more efficient way of making C02 is to mix
apple cider vinegar with calcium carbonate powder
(calcium carbonate powder is available from ebay and pet stores--
you should be able to get it for £5 per kilo).
Apple Cider Vinegar is preferable to regular vinegar because it has
a pH of ~2.0 (the same as the acid in your stomach -- so it's strong acid)
Using apple cider vinegar and calcium carbonate will generate more
C02 for you. Calcium Carbonate powder is much cheaper than
baking soda. However, apple cider vinegar is more expensive
than regular vinegar.
The recipe this chap uses for creating C02 is one cup of vinegar to
1/4 cup of baking soda. He doesn't use the gas he generates very
well, because he places his mice at the bottom of a 1 gallon jar.
And he generates his C02 in a separate 1 gallon jar.
This means, to kill his rodents he needs to generate 2 gallons of
C02 (absolute minimum). That's pretty wasteful. And this is perhaps
why his rodents were apparently knocked out (and not killed).
If he had connected 2 X 1 pint jars his requirement for C02 would
have been obviously much less than 2 gallons (16 pints).
At this point... i'm not convinced that C02 is a good way of killing
chickens... They panic and go frantic... that's obviously a sign of
high stress. The rodents "appear" to be subdued and passified by
the C02 gas.
I know that for humans, not carbon dioxide, but carbon monoxide is
an effective and painless way of dying. Carbon Monoxide emitting
heaters kill hundreds, possibly thousands, of people in
bedsit homes, and festival tents, across Europe every year.
For humans, carbon monoxide is painless, it results in tiredness...
people fall into a slumber and simply suffocate in their sleep.
I wonder if a C01 gas generator could be used rather than C02.
At this point in time, however, i don't know how to make C01.
