I've been housebound for over 12 monthswith a very bad right knee (from a nasty slip in the
bath) and pressure ulcers from being forced to sit around a lot as a result.
So I order my live insects in bulk by mail order , in my case :
800x 2/3 sized crickets weekly (to go to my 4yr and two 10month old beardies and some to my two 5 yr old bluetongues)
about 500 mealworms once every 2 or 3 months (treats for the pet lizards and I give to the local resident wild lizards and frogs too)
about 200 superworms every few months (treats for the big beardie and bluetongues)
and occasionally I order food grade garden snails for the bluetongues as treats.
I have also bought silkworms and mulberry leaves in bulk by mail order.
The all come by express post ( can take 2 days to get from the supplier to me if they have to travel 2000km ie from Melbourne to Newcastle or Cairns to Newcastle).
I highly recommend you provide your baby beardie with LOTS of high quality live insects DAILY and you work out your logistics of ensuring you have a constant supply of suitable sized live insects on hand to allow you to feed the little beardie two or even better three feeds of live insects per day.
Your choices are:
calcigents (sold as phoenix worms in the USA)
silkworms (these can be fed / raised on either fresh mulberry leaves, blanched / frozen the thawed mulberry leaves , or silkworm chow (made as a paste)
gutloaded and calcium dusted crickets
or
gutloaded and calcium dusted roaches
or a mix of the above (excellent to offer variety to a lizard).
If your hatchling is from 4weeks to under 3 months old, I'd offer small silkworms (up to mealworm size about 1.5in long) , and an appropriate size of cricket will be crickets about 25days old and up to 1/3 size.
A young bearded dragon needs LOTS of high quality insect protein and fats to grow
BTW only adult male crickets churp. (I quite like the sound.)
