Firstly the rule with feeding bearded dragons is not to feed them anything bigger than the space between their eyes. Bearded dragons are omnivores so they will eat plants and insects/animals. We find the feeding ratio to be about 30% Vegetables to 70% insects. Bearded dragons will eat almost any vegetable and occasionaly some fruit. Avoid spinach as it holds calcium and so the lizard cannot absorb it so it has hardly any nutritional value, lettuce also has almost no nutritional value as it is mostly water so dont let them fill up on lettuce. Our dragon eats large crickets, giant mealworms and the occasional pinkie (new born mouse), which we breed as we then know how healthy they are. Frozen pinkies are pretty useless, as you have to defrost them and so they are a bit cold and smelly and also they dont move so you have to wiggle them to get the lizard to eat. Lizards will generally not eat anything unless it is moving. This is what we feed our dragon, he eats about 24 large crickets a week, about 10-15 giant mealworms and a bowl of vegetables which we vary. He also has a pinkie mouse or 2 about every 2 months depending on how fast our mice breed. We put the crickets in the cage a dozen at a time, some people put 2 or 3 in a day but we prefer it this way. Then we feed him about 4 giant mealworms every 2 or 3 days. These we feed him from the end of needle nose pliers, just so that he doesnt get our fingers by accident. Then when ever we have pinkies we drop them right in front of him and he usually eats them instantly. Dragons love mealworms and waxworms but both are very fattening and too many can be bad for them. Do not ever feed any lizards insects that have been caught or that you dont know their origin as they may have parasites, bacteria or pesticides on them which could harm the lizard. Especially be aware of fireflies as just one could kill an adult dragon. Most dragons will learn to drink from a water dish but if not then just lightly mist their head and they will lick the droplets off.
Sexing:
There are a few differences between the male and female bearded dragon but you cant really tell until they are about 4-5 or even 6 months old. The easiest way to sex a bearded dragon is to gently lift its tail and look under the tails base. Males will have 2 small bumps on either side of the underneath of the tail and a female will have one middle bump or none at all. The other signs of sex are that males have a larger head compared to body size than females and males are generally bigger all over, plus the males tail is a lot thicker than the females and it is slower to taper to a point than the females.
Breeding:
We havent read much about breeding bearded dragons but we can give a quick overview. Bearded dragons lay eggs like most lizards. Females reach reproductive age between 1 and 2 years. They may lay up to 16 eggs in a shallow sand nest at the beginning of summer. Once the babies hatch they will be about 3 and a quarter inches. Baby bearded dragons need a lot more care and food than adults and grow very rapidly. Most juvenile deaths will occur in the first month but by the second month the babies should have doubled in size and bulk. They should reach adult size within only a year.
