Probably just keep marking them down, until someone comes in who cannot resist the good deal.The worker there, who got us our chicks for 50 cents the day before Easter said something along those lines. What do they do with the unsold ones? Kill them? They have to give them to a farm or something.
I know someone who was watching as the chicks got older, and got marked down cheaper, and came in the next day planning to buy them... to find that someone else bought them the day before
