Leave a cricket or two in with the cresteds .Their natural instinct is to grab and eat anything that moves smaller than them.Some cresteds seem to take awhile to catch onto that.But once they do they cant resist.
Overall cresteds are very secretive about eating and are often distracted by your presense.Leaving a couple of crickets will get them over that.
Baby food is like candy to them due to all the sugars.This might be part of it as well.The urge to hunt isnt there is they are full ,socut back on the babyfood prior to feeding crickets as well. 3-4 days not eating wont hurt the cresteds.
