For frozen feeders, how long is it safe for the food to be in the freezer before it needs to be consumed? I know I might seem dumb asking. I just recently found a local breeder and am buying from him instead if spending $7 per rat at a pet shop. Issue being is that I only have 3 BPs, an he sells 25 at a time, and only 2 of my BPs are big enough to eat the 25 that I currently have, which means with feeding once a week, that bag would last 2+ months.

How long will they stay fresh (which doesn't even seem like the right word since we are talking about dead rats here, lol)?
