Any idea why my girl would start sleeping on the bottom of the cage? This started last night, she usually sleeps on whichever perch is highest (with this set up is was usually the top left towards the front of the cage), but last night she slept in the shallow box that is usually in the back right corner. I moved the box tonight in hopes that she wouldnāt sleep in it again and now she is just on the grate sleeping (back right corner). She is very alert, if I open the door she pops up and climbs to the spot where I bring her out of the cage from. She is behaving normally when awake and her weight is fine. Is this normal or should I be concerned?
