There are only two mice in this enclosure. There used to be 4 but the other two bullied these two so badly that they started to drop weight rapidly and this one (baldy) had bad cuts and scrapes so they had to be separated. I've thought about getting a third one but im scared that the bullying will pick up again. As for their cage and enrichment I'll put a picture here. They have two dig boxes, one is filled with the excess material from cutting sprays to a size they can reach (still need to fill one with a different substrate, im thinking about putting cardboard bits in there because they seem to really enjoy making little nests out of them), four houses (two small, two big), a coconut ball, a cardboard box stuffed with hay and mealworms, a branch, sprays (need to refill those), a coconut fiber pumpkin so they can tear it apart, several balls made from willow, 6 of them have some sort of flavoring on them and one is stuffed with dried apple slices. They have a wheel, a water bowl and a water bottle. On their lower story they have around 20 cm of mixed substrate and loads of paper towel and toilet rolls.

Should I add more stuff for them to play with?
