We get asked this a lot so here is an example of how to measure safe cricket feeder size. They should be no bigger than the space between their eyes, this is most important for young babies and juvies. Crickets should be well gutloaded, feeding straight from the store or when they are not gutloaded is giving the dragon very little nutrition. We have found that even dragons who come to us not thriving well, when put under good quality lights, and a good gutload, well start growing even if they have not for months.
