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.

Though you may see chipmunks around each other, they are not social animals. They like to keep to themselves and only interact during mating season, which is in the spring.

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.
