Recently I had bought some chicken and put it in the freezer to keep it because it wasn't going to be used right away.
That was about a week ago maybe two, last night I took some of the chicken out and put it in the fridge to thaw overnight and I didn't notice anything strange. But tonight when I took it out to cook I noticed the bag was slightly puffy, not like ballooned out or anything just puffy. If I press on it I can feel that there's air in there. I wanted to know if that's a sign of spoilage and if the chicken is still safe to use?
