Lake turned pink because of algae in Victoria, Australia

It was a sunny afternoon and my chickens were busy bathing. To my wife’s annoyance, they had dug up the soft soil near a veggie patch. They were constantly throwing dust up their feathers and shaking their bodies to get rinsed with the dust. The child in me was astonished. We claim to have shower or bath to get rid of dirt and here they were bathing in the dirt!
