Chickens and Ice

With nights down into the 20s and days in the 50s, I've been going out in the morning with a jug of warm water to pour into the waterers to melt ice in the mornings. This morning, one hen Amelia pecked into the outdoor waterer and came out with a small piece of ice. Two other hens began running after her in "chicken keep away" around the far end of the coop. One chasing hen, Arrow, came back, marched straight to the waterer, pecked into it and a piece of ice flipped out. Blossom, another hen, saw it go flying, ran forward and snatched it, with an angry Arrow hot in pursuit. After Blossom ate the ice piece, she and Arrow returned to the waterer to peck out more ice, each getting their own piece. The other three hens sauntered over to check things out, pecked in and got their own. By this time, the rooster Fred decided he wanted what the hens had, so he pecked and got his own. When I finished up egg gathering and feeding, all seven were parked around the waterer pecking ice out of the bottom. Amusing behavior on a frosty morning
