Fully cooked turkey not defrosted in fridge after 72hrs

I have a fully cooked frozen turkey (11-13lb) that was delivered by honeybaked ham on Tuesday. It was delivered frozen with ice packs in the box. It’s been unpacked and sitting in our fridge since Tuesday and I just touched it, 72 hours later, and it still feels frozen to the touch. I need to serve it in about 24 hours and I’m worried that for whatever reason the fridge isn’t allowing it to defrost enough (their guidance was 2-4 days but clearly that’s not happening here). The temperature in the fridge seems normal as nothing else, such as cartons of milk or other normal fridge things, are not frozen. I’ve seen the suggestions around putting it in a sink water bath and changing water every so often, but that all seems like guidance for frozen uncooked turkeys. Can I do the same thing here given the turkey is fully cooked to begin with? If I do that early in the morning will I be good to warm it per the instructions for serving in the evening? submitted by /u/SFexConsultant
