One thing I'm always bothered by adventurers taking hunting/gathering quests is that overhunting/overgathering apparently doesn't exist. You think this is something that'd be a bit more regulated.
Unless it's another situation of "eggs only come from this bird monster", I don't get why eggs are rare, in this and a bunch of other stories. Uncommon in cities maybe, but not rare. The chicken shits out an egg almost every day, if there's a farm with chickens, there's a lot of eggs.
Everyone's talking about the mommy milkers on the XX year old girl, but I'm more worried about the population of wildlife she devastated, potentially causing entire ecosystem upheaval and resultant starving animal life.
