I have some chicken and giblets to make some soup. Family member bought it and gave me half but I didn't realise they bought it frozen. They thawed it in the fridge so they could cut it up. I didn't think and put it straight back in the freezer. Is it ok to use? I was looking online and it seems to be that if it was thawed in the fridge then it's fine. She put it straight in the fridge when bought and I picked it up two days later
