This will be our first winter with chickens. We live in Michigan so we do get freezing weather from Nov/December through March. I do not want to increase our already high electric bill and I do trust the theory that chickens will do fine in an unheated coop as long as it is not drafty but well ventilated. That part is taken care of. We have also insulated a corner grower pen as well as stacked hay on the north and west walls. We will have two flocks separated within the same coop according to age and also a separate run within the outside pen. The older hens will be in the main area and the now chicks (8 wks by November and hopefully out of my living room- although I do enjoy them now) will go into the grower pen under the nesting boxes until they're big enough to join the others. They have galvanized hanging waterers now but I'm thinking of switching to rubber bowls for winter so I can easily dump the water & ice and refill with jugs of water. I really don't want to carry the waterers in and out of the house all winter - I'm too clumsy and will spill! My question is this - will they step in the bowls and freeze their feet? I have terrible childhood memories of frostbite with our ducks and chickens. I Don't want that for my chickens. I know our setup as a kid wasn't the greatest but I don't remember how we watered. I know a lot of people swear by the rubber bowls & I like the idea. Thoughts? Other option would be buying another set of hanging waterers to alternate filling and thawing. Do the plastic ones hold up in winter? Looking at cost...$20-25 each for galvanized x 2. Also keep in mind I would be doing the same for both age groups if possible. No heat, no water heaters, nothing electric. Thank you in advance - I really appreciate your experienced feedback!
