repack frozen mice/rats?

[frankadank]

hey guys i just received a shipment of 10 mice 25 weaned rats and 15 small rats. they all came vacuumed sealed as one. 3 packages but all mice in one and all 25 in another an so on. when i go to open the mice/rats do i just take one out than throw em back in the freezer or should i than individually wrap the other 9 and put them back? i do not have a vacuum sealer or i would just use that. if it was steak for us and you take one out anybody would repackage the other 9 to keep them fresh. are rodents like that? ahahah thanks for any tips. hope everyone has a good day!
