He won't cup feed most of the time. He wants his food to free range which gets it all over and is hard to keep track of. He also will not usually hand feed because he stays at the top of the range out of reach.
thats where the line is drawn for me then.. if he wont hand or cup feed then he gets to go hungry till he will cup feed or gets caged. hah. no free ranging of bugs (on purpose) here..noooope.
if you havent, try tong feeding. OR use a DIY jug type feeder.
