Did you check the room after? Hulks can bash through walls I believe, so the fact that there were no windows isn't actually something that would stop them. It would have been strange for them to have been building up so long without trying to bash free earlier...
Didn't realize hulks would bash down walls. That was the first one I encountered in a closed area, it just smashed the door and rushed me that way (woke up with it one tile away from me, bed is right by the bathroom doors - I killed it with a full point blank burst of 20 rounds from my backup MP7). Room was still intact, only things broken were the two doors and an interior wall that I think the grenade destroyed, but it still led to another sealed room and not outside.
It's possible it was a single spawn, since after 2 days of being trapped inside with nothing to do but changing my liquor collection into molotovs, making grenades, and sleeping - some more zombies broke my window barricade and I wound up killing another big swarm of them that were right outside (and burning the house down with molotovs in the process, heh). More were in the bathroom too (thumping against the boarded up doors) but I ran off after clearing the ones outside so im not sure how many were stuck in there. Now I'm holed up in the overground portion of a science lab behind an iron door healing up. The area seems to spawn a lot of young triffids so I have an infinite source of veggies a few knife stabs away. No bed, but i'm still managing to fall asleep - and with the little lake thing right out front and my water purifier (and a huge pile of batteries in my UPS's) I have as much water as I need. Already healed up a good bit after a day there, and the turret I grenaded on the way in had several stacks of .45 ACP ammo on it. The character might just make it.
