I'll tell ya what.... feel free to contaminate your own stream as you wish, and I'll feel free to prevent contamination of mine, as per the regulations.I suggest basic common sense. If the same number of chickens is kept in pens near the stream or are allowed access to the steam the water is contaminated equal. Same goes for cattle, horse, sheep, goat, and so on pastures with creeks and streams and rivers all get contaminated, just don't overpopulate. Wild animals poop in and near water all the time. Animals die in and close to water every day somewhere. Just use common sense


This sort of "common sense" is exactly the reason that folks need to question whether their stream's water is safe for their chickens to drink.
