Here I have silkworm, cricket , dubia roach, home grown earthworm, I place each one of them to my Dickie Roll's nose for 5 seconds each, then I put them all in a feeder cup, surprisingly he aim only at the home grown earthworm which he never had before on his dinner manual, does this mean my Dickie Roll like to eat New earthly raw meat over others???? All these feeder move fast except the dubia roach, can it be the new item smell attract to his attention??? This makes me wonder.....Yup...yup
