That is true! I did think about that, and think that maybe, especially as the site grows (this is maybe something that would work better with a larger site population and more pets etc) it would even out and the auctions wouldn't suddenly be completely barren.

This might also be elevated if it was a less frequent quest, like a weekly. Would also give people time to obtain the egg they want/need and hatch it. Prices gauging could be avoided if the quest target isn't the same for everyone, a colour request could be randomly generated per person that goes to accept it (aka - I go ask for a quest, I get the colour blue. You go ask for a quest, you get green, etc). If you want to prevent people hoarding pre-hatched pets, you could also have it be a requirement that the hatchday of the pet is AFTER you accepted the quest. Although this does negate one of my original benefits, which would be a useful destination for extra pets left over from trying to hatch a certain colour.

If you make the quest require the hatchday after the quest accept, it would allow for some kind-of gamble/strategy aspect. Do I hatch the common egg that has a high chance of hatching into the colour I need? Or do I go for the rarer egg that maybe takes longer to hatch, or the egg that has a lower chance to hatch as what I need, but I'll get more points if I do? Do I try and buy multiple eggs and hatch a bunch at a time to see if I can get what I need? Etc.

With the possible addition of allowing for direct egg sales/trades (aka, putting eggs for sale in a shop/being able to transfer them to people/being able to trade them) it would allow people to sell/buy/trade eggs specifically because of the quest. Like, "Hey, I have a quest to get X colour, I'm looking for A, B, or C egg." etc.

I agree with what you've brought up, though, those would be things to consider if that kind of quest were to be implemented. 0:
