Feeding
Crickets/Locust
Most bearded dragons like crickets and locust, when Eugene was a baby bearded dragon he started on Small/Medium sized locust and crickets and was fed twice a day, eating 3-4 insects at each feed. He is now on x-large locusts and is 7 every other day.
Any uneaten insects should be removed from the vivarium before nighttime as they irritate and harm your beardie.
You should dust your crickets with Sandfire Super Foods Dragon Dust ICB, this ensures your dragon is getting all of teh essential vitamins and minerals it requires in it's diet.
Keeping Locusts
If you would like to keep a larger amount of locusts so you can buy in bulk and save more money, then all you need is a large animal container/carrier which are sold in most pet shops. Then simply put them in there with some egg crate and ensure you feed them lettuce, carrots etc to keep them alive. If you would really like to save some money you can try to breed them yourself, this requires more attention in nutrition, heat and light.
Salad
Bearded Dragons also like dark leafy greens, you can buy a normal bag of salad from the superstore (which doesn't have iceberg lettuce in it), baby bearded dragons can have a couple of pieces each day. Adult's should have a good handful, or however much they will eat. Sometimes Eugene can be picky and refuse to eat his greens until he's had his locusts.
You should also dust your salad with with the Sandfire Super Foods veggie formula.
Water
You will need to provide a shallow water dish and put fresh water in it every day. You will also need to mist your dragons vivarium in the morning using a spray bottle and then mist his head as well (he should lick the water off the viv and his head). This is essential as bearded dragons can not recognize still water and will often not drink it.
