There's no reason not to think they wouldn't. There are a minimum of two gunshots fired, and they're a decent distance apart from each other. That's plenty of time for walkers to arrive. It's also proven that they're already in the vicinity before the fight begins(one walks up to the fence before being taken down with an axe or something by Carley, unsure in Doug's case). On top of that, we already know they can topple the fences if enough of them pile onto it.
What do you think Andy's immediate goal would be if spared? Charge after Lee and his group of several armed adults, go searching for his zombified mother(i doubt he would be able to kill her upon recognition, at least initially), search for his brother who is in a trap with no release latch(and may already be dead/walker) or quickly get gas to the generators so the walkers don't get in.
He has the potential to be shot in the ear(?) and either severely beaten or(in my case) electrified on the fence. That would probably put him into a somewhat weakened state, and with walkers already in the area it makes sense that he'd die before he could recover. On top of that he doesn't see Danny or Brenda, only what Lee says(They're dead/They're not coming). He would probably look for them to try to save them, and likely be killed by them.
