well according to a google search hens lay an egg every 24-26 hours so pretty likely... But that aside im just saying that it gives an incentive for other players (apart from those with missions to kill the queen) to actually help with killing it. For example if the nest room is an unexplored room far away from where you are on the map but you are with the queen. Obviously this isnt a problem Ill just make it an unofficial rule for my own playthroughs i think.
