Okay first off I don't use a heated dog waterer I have two coops and that would make my electric go way up. My solution instead is the same one I use for my horses. I have a mud room in my house where we take our outdoor gear off and I have two water buckets for each coop and stall. I will change out the water buckets each feeding for one that isn't frozen on days that are really cold. I have a sled that I bring right up to the spigot outside so I can fill them up. Then I bring in the frozen buckets for about 30 minutes until they start to defrost and then I dump the ice outside and stack the buckets for next feeding.
I do have lights in my coops more so for light so they will lay rather than for heat and my next step is to get a timer for them so that I can have them come on early and go off after dark when the chickens are all settled. So far my bedding hasn't changed. I use fresh pine shavings and change them out twice a month when they get really dirty so that I can put in fresh. Nesting boxes are changed every other day and also use lots of pine shavings. Other than that the girls go outside and graze on the grass in the bare spots of the yard. I do give them extra treats and I tend to warm them up but other than that they seem to do well on their own.
