If you can hang on until a couple weeks after easter, there are usually a disturbing number of ducklings & chicks being given away once people realise they are nosiy, messy, & stinky to have in the house as opposed to the cute dyed fluff balls marketed at easter. You might want to post some flyers at feed stores, grocery stores, etc. You may get lucky & find someone who was toying with the idea of getting rid of their birds but hadn't gotten around to advertising yet. Also check w/ 4H & FFA clubs.
