i think a few day is not the best suggestion.i think u should wait until ur bp is comfortable in his new home.sometime,if u dont provide good husbandry for ur bp,it still wont eat even u give it a month period to de-stress.so my suggestion,check again ur husbandry(send picture of ur setup so we can give more opinion),let ur bp comfortable with it new home,until u r sure that it ready to eat.
