Pellets are very unhealthy for gliders and should not be used for their diet. I recommend that you order Original HPW mix online and make that up for them. You blend together the protein mix and bee pollen they send you with cooked eggs, honey, and water, then freeze it. They just get a scoop (1 TBSP) each night like ice cream, but it's good for them. In addition you must feed fruits and vegetables each night, about 1 TBSP of each. You can use frozen.
