My baby beardie started doing this... I think I spoiled him by introducing him to silk worms. He wasnt eating when I got him due to time to adjust but after that I got silk worms for my cham and dropped them in there and he loved them. Now he doesnt seem to eat the crickets as much, he did eat one today but he would tear up 5-6 in a matter of a minute or so before the worms. I dropped wax worms in today to see if he would be interested and he didnt even hesitate for them. Idk why they do this but it is annoying, considered the silk worms are a once in a while thing since i have to get my dads credit card and wax worms arent healthy.
