We know that chickens love and need to dust bathe, so I provide them with wood ashes and sand for bathing. We add sand because it helps to weigh down the ashes. I use it on the floor of the chicken coop, but I'm sure that dry soil would work, too.
Emptying a few cans of corn into a muffin tray, adding water & then freezing it is a very small act of kindness. But on hot days, it means the world to the chickens that live here. Pecking away at an ice block to finally be rewarded with a cold corn kernel is a great way to help them keep cool .
