I am new to owning a beardie, actually my son's but I spend the most time with luigi. 1) we are not sure how old he is 2) we are limited to meal worms (which we don't feed often), horn worms and crickets. We want to be able to switch it up like we do his veggies. I would say he is about 6 months? Lizards are not huge in our area
Can you post some pictures of him? That will help us determine his general age. You can upload pictures here https://www.beardeddragon.org/useruploads/ and post them to your thread using the XIMG button when you reply.
Those are good items to offer on rotation. He will need a variety of veges too, especially when he gets older (over 1 year or so). There are some good ideas for veges here http://www.beautifuldragons.com/Nutrition.html
What do you have in place for lighting for him? It's important to have the lights just right so he can grow up to be healthy and happy.
