I didn't watch the almost 4 hour video, I'm sure there's some good info but there are just a few main things that we can all do to try to keep our beardies healthy. Don't over feed them but don't underfeed them. Over feeding is the practice of " all they can eat in 10 minutes 3X a day" for for babies + juveniles with some eating over 60 a day. Something I never did or never promoted myself. That is how some owners raised them and it led to many overweight dragons and contributed to or caused health problems. One thing to notice in the shorter video that I posted first is that they show a 10-11" dragon, not a hatchling, eating a dubia the size of the dragon's head. That size is just on the brink of being too large which if it WERE too large could cause impaction. But anyway, a beardie very well would be filled up by 4-6 of those huge dubia but not everyone can get those. To make up for it [ and to use bugs that are a a safer size ] a person might offer 10 -12 or so medium crickets or large bsfl. So the TYPE of insect also matters. If you can't have dubias, the other insects are going to be the staples and you might need more. Superworms and mealworms are not too good for beardies, especially if fed in more than 2-3 at a time, so they are not a good choice as a staple feeder for babies. Going back to hatchlings and up to a month old, they need VERY small bugs, no larger than 1/4" [ even slightly smaller ] for the first few weeks and then 1/4 to 3/8 size crickets for a month old, allowing them to eat twice a day about 10-12 at each feeding. Shredded greens should be offered first, before the insects. Once a dragon is in the 10" and larger, one feeding of insects a day is fine, about 10-20 is good depending on what size the bugs are. If they're a bit on the small side you give them the higher number. Dragons that are in the 15 + range can handle larger prey items and the number can lessen to 5-10 a day, again depending on the size + type of insect. Adult dragons are the ones that only need either a few large insects per day or 5-6 every 2-3 days. Last but not least, my 2 boys are in brumation as they do every year and will be 12 this spring. They are neither overweight nor underweight and eat both insects [ including superworms as adults ] as well as greens and have done so all their lives.
