I'm thinking of where best to locate the fountain. It seems like inside the (walk-in) coop would be best for keeping it cooler in summer and from freezing in winter. I am liking the idea of the ABILITY to hook the fountain up to a hose in the non-freezing months for when I want/need to leave town for a couple days. But I do NOT want to mess with insulating the hose for winter. I plan to have my garden spigot right on the edge between the chickcoop/garden border, so I can easily run a short hose through the coop wall that can be connected as needed to the fountain (or whatever waterer I end up using) on the inside of the coop, and which dangles from the outside of the coop wall (thus draining automatically when disconnected). This could be hooked up outside at the spigot whenever we needed to refill the fountain resevoir. So my question then would be how long will that 1.5 gallon of water last in the winter if it's coming from a fountain, as opposed to from a traditional waterer? Would it be possible to enlarge the resevoir so that someone who didn't want to use the hose continually but only to refill it could put in more water to last longer? Also, I wonder if I put the waterer inside the coop, then when the chicken door is open to the run during the day, won't that allow the inside of the coop to get as cold (or as hot) as the outside temp, and thus, returning to the freezing/hot water problem?
I don't know if this is making sense, or if I'm rambling incoherently from one thought to the next--I tend to do that more as the night wears on.
