flirty.. i dont know anything about the MHD but my baby beardies (19g and 40g, approx 10", hatched around august) both love their greens, always have since the day they came home... the breeder starts giving them greens right away too. They almost give me dirty looks if i dont drop them by 7am ... they do love their crickets but love their greens just as much. Im going through a bag of spring mix a week with these girls, and very little gets wasted. Im averaging about 600 crickets a week between the two of them... Nikon (bigger) is more of a hearty eater so when Canon catches up im sure we will be going through about 1,000 a week between the two of them, for the record they do NOT live together and while they do require a bit more attention for diet, lights, exc its worth it to me because they are so interesting and entertaining. i cant wait until they get a bit bigger... canon and nikon were both about 6" when they came home. Mine have never once lunged or even had open mouths at any of my family.... actually your response is the first time ive ever heard of a beardie lunging...
for the record.. my breeder charges approx $40 per normal beardie baby... if you go through a breeder you might be able to not only hand select your animal but also get to ask lots of questions, hatch dates, diet, exc.
just my .02 and experience
