A thread just for us Canucks! That's great!
I'm about 50km south of Prince George, near Hixon. I bought a home on acreage back in November, and it came with chickens and muscovies. Having a lot of fun learning all about home poultry, and enjoying the magnificent eggs.
Typical Canadian story: Household water is on a cistern, with water being trucked in. There is an old well with a hand-pump on the property, and previous owner told me in all his years of living on the farm, the hand pump has never frozen up, no matter how cold it got, and that is what he has been using to get water to the chickens daily, as it is near the coop. The water is a dark yellow, so I won't use it, but that is what was being used for the livestock they had.
Well, we've had brutally cold extended weather, in the -20's to -30's for over a month solid, and yes, the hand pump froze up. I had run out of household water and couldn't get any delivered because of too much snow - the water truck didn't want to risk coming all the way out to the boonies and get stuck. So . . . I took my wood splitting axe and hacked a hole through a foot of ice in the duck pond, and got the chicken water from the pond! Of course, had to re-open the hole on a daily basis, but the birds got water, and despite the cold, they were happy and laying pretty regularly.
Now that the snow is melting they seem to prefer drinking out of snow-melt puddles - I think they got a taste of "wild" water, LOL.
