It also depends on how cold your freezer is. My chest freezer is set a lot colder than my refrigerator/freezer unit in the kitchen so anything that comes out of the chest freezer needs extra time to thaw.
Usually I pull rat feeders out of the freezer and put them in the refrigerator overnight to thaw. Larger feeders may take more time - rabbits for my retics can take 4-5 days to fully thaw in the refrigerator because bunny fur is a great insulator.
