| DUCK EGGS ARE BETTER FOR YOU!
GRADING DUCK EGGS-This
is usually where the USDA comes in and assigns egg grades but so far
they do not require this for ducks.
HOW FRESH ARE YOUR EGGS?-As an egg ages its proteins in the albumen denature and become thinner and the yolk gets flatter and sinks into the white. A
fresh egg has firm albumen and a full looking yolk that sits on top of
the white, when cracked onto a plate the egg stays in a circle as
opposed to running all over the plate. Candling
the egg, or placing a very strong light behind the egg in dark
conditions, is another effective way of evaluating its grade and
freshness. The yolks will spin more freely and closer to the shell the
older the egg and the air cell will move easier than it would if the
egg white were thicker. A bad duck egg will have a neon
yellow tinge to the white while a fresh egg will be perfectly clear.
Note chicken eggs normally have a dull yellow color.
