I just give mine plenty of water, too. What breed do you have? Runners? I believe runners do better than many other breeds in the heat.I put a half of a bucket of ice in there water with electrolytes/vitamins for the night. was a very hot day for them. Does anyone have more ideas to help ducks keep cool at night? I dont give them food at night. I just give them 5 gallons of fresh water. I have seen people talk about fans. I dont have one they can use right now.
