OMG! Funny or what........ I was checking my girls in their brooder and had my iced tea with me. As I watched them, it occurred to me that they don't know what an ice cube is. Sooo ....... I tossed one in and..... BAM! They all attacked it and played hockey until it melted. Riot!! BTW, I have one of those ice makers in the frig door so the cube was only a "slice". Try it on your bored birds!
