Duck eggs are bigger, and have stiffer whites.
Some people prefer them for baking because -they say- they hold moisture better, and will make your cakes and such moister.
Our duck eggs are great! I actually like them better than chicken eggs, which is weird, since I don't even like eggs.
Duck eggs are Alkaline (base) and chicken eggs are acidic.
Cancer patients seek duck eggs because they think by changing their body's 'environment' that the cancer will somehow be less likely to uhh... breed??
DUCKS. WILL. PLAY. IN. THE. MUD!!!
Don't let them have medicated feed and keep doing research! You'll love them if you decide to get a couple. ^-^
They're funny to watch.
Try geese too! They have WAY more personality than ducks, and aren't as stupid. (Too bad I didn't get MY goose a mate! Have to correct that soon.)
Geese will mow your lawn, and ducks are really good pest control.
