I know and what scares me is I have 2 watering dishes that been empty by the time I get home. At night (after chickens goto bed) I sneak off with the 1gal waterers and wash them up real nice like. Then I fill them with about 2inches(1/8th full) of water and freeze them. That way when I go out in the morning to let the birds out (waterers now full of water+ice) I feel the water will not boil by the time I get home. I just got those chicken water nipple thingies in the mail. Thought about maybe trying those out though I am afraid to "trust" the chickens to figure it out with all this heat. Thought was mount a pvc "bar" and put a 55gal water barrel to feed it. Questions? Comments? Constructive advice?
