A good fall cleaning is in order here also, will be getting to in in the next couple of weeks.
Do you have a vacuum sealer? We have one and love it for chicken and fish, among other things.... we cut the bags bigger than needed the first time and wash them and reuse them for slightly smaller amounts the second time. We have kept fish filets for 2 years with no decline noticeable when used. As long as the vacuum seal stays good they keep for ages. We do use zippy bags for short term stuff, but always seems something gets overlooked and ends up freezer burnt.
No, we just use ziplock. Things never stay around long enough to get freezer burnt or go bad. Since our bulldog mix has such bad allergies, she has to eat raw, so the chickens we process are usualy her meals for the next couple days. Someday, after she's gone, we may invest in one.
