Not really, @rural mouse 's suggestions on cords and what to do were great. As far as waterers, I use a heated nipple waterer, got it from Premier I think. I also use a heated doggie bowl, but they evaporate quickly, so as @rural mouse ? said you might have to be filling it often if you get that.Thanks! Do you have any suggested ones? May have to get one longer than 200ft or connect a 200+100ft together.I officially love those girls (and guy).
I didn't think I needed heat, but I saw a brooder heater in one of @BY Bob photos.
Right, you don't need a brooder heater or a coop warmer for fully-feathered pullets or chickens, @BY Bob had that there for his young chicks when they weren't fully-feathered, and now it's handy for after-swim warmups.

I have one like he has but mine got quite hot, too hot to touch and so I didn't trust it in the close quarters of my coop. I used a heating pad they could stand and sit on instead, but only while they feathered out. I have that stand-up coop warmer now for horizontal use under the red worm bins in our very cold work room, for winter use for the worms.
But chickens do need to be out of direct drafts, yet have really well-ventilated coops. There are very good articles on ventilation design here on BYC.
