All these cute and fuzzy animals come with years long commitments. They make amazing pets if you're prepared with the proper brooding equipment and housing... they're really not hard to raise either but like every baby I've ever met, they require a lot of up front care and they tend to make a mess. So a little research and some inexpensive equipment will go a long way.
Domestic ducks have very low survival rates on wild ponds and a lot of folks also don't realize that baby ducks that aren't being raised by a mama duck can't swim. Well, they can swim for a few minutes, then their fuzzy down becomes water-logged and they sink underwater and drown. Additionally, who will warm them after a dip in the cold pond? Other mama ducks won't accept them into their little brood so don't expect to find an adoptive wild family either.
Duck dumping creates complicated problems for wild ducks and their natural habitat, often upsetting entire ecosystems of waterfowl populations. Domestic animals compete for limited food with wildlife and may even breed with their wild counterparts which reduces the genetic fitness of wildlife populations. There is also a real possibility of introducing domestic diseases to wildlife that have no immunity. This may cause die-offs, sometimes on a massive scale. Think of the first Europeans landing in American and spreading new diseases to the indigenous population... ugh!
So if you have any Easter impulse-buy ducklings, goslings, chicks, or bunnies that you need to rehome, here are some folks in Maryland (and one in Virginia) who are already raising farm animals and are more than happy to help. You can contact them through their facebook messenger:
