Once you adjust your husbandry, give them 7 to 10 days without any handling (if possible).
Once 7 days have passed try to offer food preferably the same kind of prey they used to eat prior to you acquiring them.
While Oakley might still refuse food (due to the stress of having to treat him daily) I would still try to offer food and see if after a week in his new environment he will take it.
Good luck.
