I've just recently attached my hutch and run together, so my girls are enjoying the new freedom. Molly spends most of her time in the run, munching on hay or flopped out. Milly prefers flopping out in the hutch (its above the run so maybe she feels safer higher up), but will go down into the run for munching and a snuggle with Molly. I also think they are liking the increased space and the fact they can be separate sometimes as although they are littermates, they do have disagreements.
