Can you share the PPM of ammonia build up in your refrigerator and the humidity levels, over the course of a week?
If not what you have is unsupported non-quantitative anecdotal claims not evidence...
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. I'll pick up the test equipment and test the ammonia buildup in the fridge and post as many results as you like online. I don't mind. I do think the large chicken sized hole in the side is going to equalize atmospheric composition and reduce any differentials to insignificant levels, but I'd be pleased to prove it with photos, videos, and so forth.
Actually all
you have is "unsupported non-quantitative anecdotal claims not evidence." what I have is physical chooks which I raised this way which are 'hard', or feathery if you like,
evidence.
If you took some tracer smoke and held it at that single vent hold and observed the airflow in real time it would be clear as day how poor the ventilation is and you observed that tracer smoke at the opposed end of the coop I suspect it would be hardly moving at all..
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.
When you are talking about passive ventilation, high and low vents at opposite ends creating a natural cross siphon effect is ideal and provides superior ventilation...
It provides more ventilation than is necessary and that excess removes precious heat from the chooks. Yes, mount Everest's peak has great ventilation, for sure, but it's bit much for most people, like your arguments without any photos or science or anything but enthusiastic sounding guesses.
[...]but I will guarantee it won't work for the northern climates of the USA or Canada.
Oh no you won't.
I'll be happy to send BYC money or prizes in escrow if you do the same dollar for dollar. They can award them as prizes.
It is far too easy for people to DO this with freezers and fridges in the USA and Canada and post pictures online. You'd lose. I'll bet on it if you do the same.
