all great points william212 about the grazing and opportunistic feeding (if in wild seems that that's how food would come along, not in a drove of 50 or so crickets all at once
) and imposed feeding schedules they get while in captivity. I imagine with out getting all cerebral on the topic that an imposed feeding schedule would be more convenient for the owner and the beardie would learn to adapt and eat when those times happen. My own beardie has taken to standing where the 'salad bowl' goes in the morning after the lights have been on for 45 minutes or so and looking at me to deliver it...LOL
As far as leaving crickets in the tank, being a new owner, convenience, and the myriad of other things that one obsesses over in making sure the beardie is healthy, warm, well-fed, tamed, etc...I would personally not leave the crickets in the tank or feed them in the tank to begin with (in the interest of time and having to chase them down before lights out). I feed our girl in a separate bin where I can keep the cricket massacre contained (calcium powder, cricket legs and cricket poop are usually left after the killing spree). She is never going to have to fend for herself in the wild (God forbid unless she breaks out and runs away and lives in the bushes in the back yard for 3 weeks until I find her again - seen many of those stories on this board) so I'm not too worried about keeping her hunting skills at optimum levels. They do seem to get spoiled easily though, so I try not to baby her too much and make her chase the crickets around the bin instead of dropping them right under her nose.
As far as the baby not eating much since the OP started this thread, I would say it's probably relocation stress, and yes, I would keep the feedings on schedule for your own sanity. Babies won't eat for a number of reasons:
Relocation stress - may take a week or two for them to adjust. Keep handling down 5-10 minutes 2X a day.
Crickets might be too big and baby is intimidated. Make sure they are smaller than space between the eyes, error on the small side.
Too many crickets presented at feeding time. 20 crawling bugs around a baby might be too much for them to deal with. Try dropping in 1 or 2 at a time.
UVB lights might not be optimium. Everyone advise to use the Reptisun 10.0 tube bulb that spans across the tank- no round UVB bulbs.
