I have read the best news of the day, So happy to hear how everything has worked out. Sorry about RB having to be let go but sounds like he has gone to a wonderful home. It is always so nice when things settle down especially when winter is ahead of us and it's nice they can have nothing to add to that stress. as far as heating in the coop none needed all are wearing a nice covering of down under those feathers all they need is to be able to keep dry and out of heavy wind rain or snow, but they may choose to be out in it just give them a choice. I keep all my doors open to their house daily and they can go inside anytime they want. As far as keeping water open and not frozen you may want to look at TSC or your feed store for heated water buckets. They are very safe. made to use for livestock. and work on thermostat so they only run if it gets below 35. I have a 5 gal for my geese and 2.5 gallons for my ducks/chickens. Just don't sit them inside something where water will gather RURU had one of her geese electrocuted because the heated bucket was sat inside something and water accumulated around the bucket. Maybe she will explain it better. But I really like using them I have had a couple of them going on 4 yrs .
