It has been so hot that I decided to use a plastic container to make a block of ice to put into the waterer. So today I brought in the plastic 1 gal. waterer, scrubbed it out, and dumped in the block of ice as I filled the dome. But it didn't fill, so I looked it over and found that I had busted a hole in the top when I dropped in the ice. Duh. So I had to get out the winter metal waterer and run out to buy a new plastic one. So now the weather has changed to a nice cooler drizzle, and it's probably 20 degrees cooler than yesterday and the hens don't really need ice in the water. Sheesh.
