I'd be happy to co-operate. I don't have such a rare piece of equipment here, so if you're not simply talking rubbish but are actually interested I'll happily allow you to shop on ebay for example and post it to a friend of mine.
Sorry I'm not your charity, and it's not my job to finance your argument, but I will take that is a no that you have no quantitative evidence...
I'm really sure that your zealous disbelief would render any great efforts to provide evidence useless. You can't make people believe what they do not want to believe when they have made up their minds to the contrary. Also, I'm not tear-gassing my chooks for some random person on the internet. LOL. Hilarious.
" tear-gassing " LOL. tracer smoke is non-toxic and won't harm the chickens, especially if you have decent ventilation like you claim that should remove the non-toxic non-harmful smoke in no time flat...
It provides more ventilation than is necessary and that excess removes precious heat from the chooks.
Any quantitative data or evidence to support this new claim? As many of us know all to well, in freezing temps too much ventilation is an oxymoron, cold weather tolerant healthy chickens don't need heat so retaining it is absolutely unnecessary, but they do need good ventilation to remove humidity and ammonia gasses that have a high probability of casing harm...
In the end your argument is still an anecdotal logical fallacy as I stated...
May I ask how much experience you acutally have keeping chickens (or any poultry) in extreme cold weather?
When I say extreme I mean temps of -10°F (-23°C) or colder for days on end as is common in many ares of the US...
Is it safe to assume you have about zero experience at keeping poultry in extreme cold climates?
How about snow, do you get much in your location and have experience with say snowfalls of say 12" (30cm) or greater over the course of a day or two?
