I'm researching whether or not I want to build a coop and raise chickens for eggs. I live in Salt Lake City, UT (not too cold -- we may have 1 night a year that hit's 0 degrees). I take comfort from reading many posts on here that chickens can survive this cold weather without a heat source, as long as the coop is sheltered from drafts and weather. Is that right? I assume if the Northeast is below 0 regularly and you're not heating your coops, I shouldn't need to either? My main question relates to electricity -- I'm guessing I'll need a heat source to keep the chicken's water from freezing, right? My planned coop is about 25-30 feet from my house, in my backyard. I called an electrician to see how much it would cost to run an underground power line from my house to a coop, and he quoted me about $1,000 to trench and lay the power line. That's a high price to pay just to keep water from freezing. Is there any other way to keep water from freezing (and perhaps provide a bit of heat on those frigid winter nights) without having to run a power line? Thank you!
