Hey All!

I have a dwarf peach sorbet blueberry in a pot 7a zone. I am not sure if it is my crazy imagination, or if I am correct, but I feel like any time a blueberry is on its way to becoming ripe it disappears. I do not see any sign that an animal is eating it. Would I see remnants of that around the plant? Or do they literally pick off the ripe ones and leave with it?
