I noticed that I am only having one of my chipmunk friends eating the food. This made me do a search on chipmunk social structure to see if they stay in groups. They do not.
I had always assumed the two smaller chipmunks, Franz and Franz, were the children and Hanz was the mother. Maybe I was right and two of them have scampered off to other areas. Though I thought they would want to stay around a sure source of food. I can’t actually tell which one has stayed since the only way I told them apart was by their sizes and behavior relative to each other.
