Just have to jump in on this discussion and hope to have useful input. We are in frozen Minnesota. I have 3 of the 1 1/2 gallon blue 25Watt dog water bowls for my birds and barn cats. I leave them on 24/7. I have used these dog bowls for 2 years now and love em.
Water is changed twice a day as I have call ducks that also use them. To keep the water clean - each bowl is half covered with a scrap of board. When I change water, this board is used to stir the water to remove all dirty sedament. I also am using the 25w led bulbs that give 75w of light. We deep litter, using DE on damp spots then cover with new wood chips. Ducks and chickens mingle in the whole barn during the day time and sleep seperated. My barn is dry and fluffy and my poultry are active, happily chatting amongst themselves and I feel they are comfortable.
