I'm no expert, but this sounds like awfully extreme advice for a 5 month old beardie. It does not sit well with me, personally.
In most cases, if you offer everyday, they will come to accept veggies. For some, it happens early on and for others (like our dragon), it happens later. Our beardie got off to a very a slow start due to a poor
UVB bulb that we had purchased initially, so when we upgraded her enclosure she was very concentrated on growing and live feeders. And grow she has, but still has some ways to go in catching up. In the meantime, I kept offering the veggies every day, and for months she just wasn't interested. She is now 8 months and for the first time is eating veggies everyday. Recently, I have had good success with consistently giving her the "moving salad" that is, phoenix worms with greens on top. She didn't like it at first and seemed put out, but she wasn't willing to let the worms just swarm about in the collards! :wink: Initially, she would get at the worms by picking around the greens and occasionally, by accident, eating a few of them. Now, several weeks into this, she is eating the greens along with the worms, and it appears that she enjoys both. (For a time, I think she just realized that if she got rid of some of the greens, she could see the worms better though. :wink: )
Juvies need lots of protein, as they are growing rapidly. I would be reticent to pull live food for that length of time to force the greens issue as for most beardies, if offered, they will get there in their own time. IMO, 5 months is too young for that kind of tough love. And in the meantime, just feed all those greens and veggie goodies to the crickets... beardie will get them one way or another. :mrgreen:
That said, if you're interested in trying the moving salad, I highly recommend using a worm feeder such as phoenix, as they have a decent fat/protein ratio (can be used as staple), or perhaps silks. Worms are much easier to cover with greens as they tend to stay in the bowl. I've tried with crickets, and they all just escaped and jumped out. :roll:
Just my .02 for whatever that's worth. :dontknow:
The best,
