Its basicly the same here, and oh and just to add the chicken barns (at least where I live)
- Cleaned out completely
- Disinfected
- Washed down
- Very carefully the bedding and necessities are redone
On top of that everything is watched rediculasly closely, temp levels, air quality, etc. you can even pinpoint how a chicken died just by the way it fell, im not joking. Anyway I live in the near heart of ontario with alot of the farming industry, and I have seen alot of their methods, sometimes even had to do some, and from what I can tell, at least here anyway, they make things as humane as possible.
