Give them a few days to start venturing out into the cage. They WILL in time. MY personal opinion is to leave the food 24/7 for a couple of days, maybe three until they get used to their new surroundings. At 33 days, they've been taken from Dad & Mom AND moved to a totally new place. Don't rush them. Let them settle in and get used to everything...........you got them at a good age.......you'll see a big difference in a few more days, when they get more confident.
