Hi Gerry. You just need a small tank - mine is 10 gal and got it used. She's only in there for about 15-20 min. I have a flat top stove with 2 lights shooting down, put down a towel then set the small tank on there. It's warm from the lights and I go get some crickets, put in vitamins or calcium all in a plastic bag and shake it around. Then as she watches me, I shake down one cricket at a time. She starts off catching them fast, after about 8-10 she may let them run around the tank. After 15 minutes I take her out - put her in big viv and then if any crickets are left in the little feeder tank, I shake them back into the container they stay in.
Hope this isn't too much detail - but it works great and most days I do this lunch and dinner. If I'm out, then it's only once. She has her veggies in her big viv all day till I take left-overs out around 6pm. Not that I expect you to have a stove like mine - but others have said beardies don't like a cold tank..........however don't need any real light set up. Sandy gets worms from time to time, and I just put them in a little dish and hold it at her face in her enclosure - not the feeder tank. If I were to be away, the reptile supply or pet stores have a cute dish for worms, so they can't crawl out. Then I would have one and leave it in for the day.
Getting into the routine lessens the anxiety. I was so worried when I first got her. But - like babies, you get into the swing of diapers, feeding, sleeping and it becomes part of your life and isn't a bother.
