My dragon is eating mostly Fluker's Buffet Blend for adult bearded dragons daily and 7-10 crickets with calcium/phosphorous powder every 2-3 days. He's provided with green leaf lettuce with powdered calcium/phosphorous most days, but barely touches it. I try to add in different veggies and fruits when I can, but he's picky and we just don't keep a lot of varieties of veggies around the house. I'm worried that this diet isn't sustaining him. Do you think this is enough for him? He's 5 years old.
