If you thawed it in the fridge and it hasn't been out of the fridge for very long, then it's good to stick back in. It's never unsafe to dump it, though, so that's the option that I go with if I get stuck with one (I thaw at room temp though, so it's a different story).
Nope, thawed with warm water, took a very short time, and then right after she refused i put it in two ziploc bags and its in the freezer right now
