Tossing in my two cents on the issue, never fed your dragon something wider that the space between their eyes because thats about how wide their throat is. A dragon has a hard time spitting something out so its better that you make the choice on what they get to eat. If i was you i would save every adult roach you get, they live a long time if they are taken care of every 2 weeks or1 week if you have alot. If you keep them warm, around 80-85 or a bit warmer they will breed. In my experiance, haveing 4 dragons, i only have to buy them food every 2-3 months. they love their roaches and greens which i grow myself. Hope i helped. good luck.
