My two cuties have been in their new, much larger, cage for 2 weeks now. I know they are happy because they sing and chatter all the time. They, however, stay on their perches and never go to the bottom of the cage. I'd like for them to play with the toys that are there and maybe take a bath in their little tub. Any suggestions on what I should do or should I just leave them be if they are content on their perches?
