This is why we are all here- to learn the lesson from others before we have to experience it - thanks for the big heads up!I don't know who started it. They were playing tag with one of the babies when I walked out there. One would have the prize and the other's were chasing and trying to take it like they do with any other food (like mice or caterpillar's if they spot any). The noise from the peeping chick's hatching is probably what drew the attention to them.
