What do you mean, "put them in the freezer"? I know that you are asking whether you should put them down or try to save them (and unfortunately I do not have an answer for you on that)... but if you do put them down, definitely do not just stick them in the freezer!! You would absolutely need to find a more humane alternative to doing this, as freezing is a slow (and I would think painful) process

Sorry if I am misunderstanding.
