Can I refreeze marinated chicken?

Holy crap, what a load. You can refreeze them as many times as you want. Most of the frozen meat you buy in stores has been thawed and refrozen. I know because I worked at a packing house and they'd take pallets of stuff out of the freezer to make room for fresh stuff and it'd sit in the aisle with blood pooling under it until they had room again. It'll be fine, it loses a bit of flavour each time you do it is all.
