My chin goes in her hammock long enough to poop and then she is back out again! I had never seen her use it until I temporarily removed a ledge that she used to get into the hammock. She spent quite a bit of time trying to figure out how she was going to get into it, and eventually figured out a way. I was going to move the ledge to another area of the cage, but after witnessing her dilemna, decided to leave it in place. My chin doesn't go in her tube much either, but will bound in one end and out the other. I know other's chins use theirs a lot. It just depends on the chin.
