That it great they are now successfully weaned, congrats lol. Maybe Mojo is a boy? With all those whistles and chatting you would have thought male...but perhaps not. Can't wait for pics. 
LOL! It's perfect that you have them since they were tiny babies-it's easier to introduce as many foods as possible.Well I put a couple pieces of brocoli in thier cage with a clip (like millet spray) and they think its a new perch.. lol Oh wait! One of them is piging out on it now!!
