The bunny hutch main doors are open all the time. The “bedroom” hideaway area is usually closed (I only open it every week or so to wash the bed)… Last night I opened it and found it FULL of hair and hay. Did my bunnies have a fight, or is one of them making a nest? (The hay isn’t near the hutch, so one of them brought it up there)… They are not fixed yet, but they are both girls, so they can’t be pregnant. Thanks!
