Sorry, I should have explained really! I'm thinking of getting the bun's new hutch custom made, and to allow them a bit of extra space in the shed I thought if the legs were longer than normal, there'd be room for them to hop and lie underneath. It would be ok for my current buns, but they're small, and as they won't be around forever and it'd be good if any future medium sized buns would fit underneath comfortably as well.
