If all of us pokefarmers new what the rare eggs looked like and got what we wanted from the shelter the crappy eggs that everyone owns would be sitting there with no owner.If they have no owner they will never hatch and it will clog up the shelter and who wants the shelter to be full of crappy eggs?I shure dont!! people who dont want the sHelter full of crappy eggs edit this and say what you think!
To the above: no, YOU don't get it. If eggs aren't adopted, or Pokemon aren't adopted from the shelter, they are released into the wild after a time. So unless you feel sympathy for pixels on a screen, leaving eggs in the shelter does no harm, and does NOT clog up the shelter. Yeesh.
