About midnight last night I took a pack of chicken leg portions out of the freezer intending to put them in the fridge to defrost overnight and during the day today, to cook tonight. However, I got distracted and left them out on the worktop. I've come down this morning and they look completely defrosted so I've put them in the fridge to use tonight. Will they still be safe to use after being left out defrosting all night then spending the day in the fridge?
