Every thirtieth turn, all roach queens that can sense the player will lay roach eggs in every open space around them, with the exception of open yellow doors, scrolls, force arrows, and trapdoors. If the roach queen moved on the turn she spawned, she will not lay an egg on the tile she moved from.
Roach eggs don't move.
In Webfoot DROD, roach eggs became roaches after only three turns.
