My budgie flies now!!

My yellow budgie (Tweak) now flies! It’s like he got his flight feathers overnight! I got both around the same time. My blue one (Pietro) hasn’t gotten all his feathers in yet but I’m happy at least one of them can fly now. I let them out and they generally stay around their cage and leave and go back in when they are ready. This picture is about 2 months old but wanted to throw it in their
