I appreciate your giving the birds room to fly, they look well-taken care of and happy as they can be in captivity. I am new to budgies but learned quickly they like branches to perch on over pieces of wood. Please give that a try, drill holes in the ends of suitable branches and install them with screws like you would a piece of wood. Or hang them with rope or chains. I have two crazy young budgies. They love these friends of nature you tube videos so much I play them for them regularly using a laptop.
