My (baby) Ball Python took over a month to get comfortable enough to come out of her log (Her hidey hole place) on her own. She just got upgraded to a new tank and is reacting the same way she used to (except when I put my hand in her cage, as now she tends to wrap around my wrist. ^.^ ) They are just adjusting to their new homes!
What worries me is that you said you feed yours in its own cage! Everyone I've ever talked to says not to do that so that they never confuse your hand for food! Naga (My baby) has a ten gallon (That she has never lived in) that I feed her mice in, an a new twenty gallon long tank she lives in.
