I would definitely not recommend dumping the whole bag in there, especially if the beardie was just relocated to your home and is still adjusting, their appetite is usually not as big when they are in a new place! If he/she doesn’t eat them all they will die and make the enclosure smell really gross and it’s not fun to clean up! I bought a small container with breathing holes and put some food and something for
hydration in there to keep them alive, I then use tongs to grab the crickets and put them in a ziplock bag with calcium powder in it! I shake up the bag to get them coated and then use the tongs to feed my dragon one cricket at a time
