Only feed enough crickets that your bearded dragon can eat within about 15 minutes. The insects you offer your beardie should be NO bigger than the space between his/her eyes. If they are too large, they can cause your dragon to choke.
As your dragon grows, the intact of insects will decrease and you can start to feed them about every other day. Instead start feeding him/her vegetables on a daily basis.
