Quite plausible, but also unlikely. What animal in the woods is large enough to accomodate a face hugger? Not many, and depending on where the woods themselves are, perhaps nothing. A bear or wolf maybe. Certainly not a bird or squirrel.
I like the idea that the outbreak of the Predalien on the ship causes the necessity of the surviving predators to abandon ship and detonate it like in Alien (a great parallel, don't you think?). Anyone have any clue as to what the story is? Is it even based straight after AVP or is it so and so many years after? Is it an Army convoy headed to a secret facility in the vicinity of the town that has recovered debris and perhaps 'cargo' from the aforementioned detonated ship the Preds are after? Wow, can't wait to see what actually happens.
