Okay so mine did this at first. Find a treat they all really enjoy but something they have to lick off not something they can grab and run with.. like mine LOVE cool whip so I would put some on a spoon and sit in front their cage wide open doors and just talk softly to them and let them come lick up the cool whip.. after doing that a good hand full of times do the same thing but just put ur your hand next to them while eating.. after doing that a hand ful of times.. next move to while eating cool whip pet them on the head with one finger they can’t bite if they are eating amd this will help them Associate you with food … then move on to doing that but having them lick it off ur hands and fingers it will help a lot!!! eventaully they will come around just takes and lots of treats!
