Everything You
Ever Wanted to Know About Chicken Eggs

White or
Brown?
There seems to be
a lot of debate about which is better, white eggs or brown, and depending where
you are you are likely to get all sorts of answers. The French, for instance,
believe the darker brown an egg is the better it tastes. They've even developed
a breed, the Maran, that lays eggs that are a deep chocolate brown. So what is
the difference between white and brown?
It basically
comes down to breed. Some chickens lay brown eggs, some lay white eggs, but it
goes deeper than that. Breeds that lay white eggs tend be leaner breeds that
handle extreme heat very well. Brown egg layers tend to be very large with
thick feathering making them more suitable to extreme cold and more susceptible
to heat stroke. Because of this most eggs sold in the southern United States are
white and most of the eggs sold in the northern United States are brown.
Are there
other colors of eggs?
Yes, some breeds
of chickens are known for laying blue eggs. This might be because a few
centuries ago some chickens bred with pheasants who have colorful eggs. Hybrids
like these are unusual but not impossible. As far as I know no one is currently
trying to make new lines of these hybrids.
Ameraucana,
Arucauna, and Cream Legbars are three breeds known for blue eggs. When these
birds are bred to a brown egg laying chickens the resulting hens will lay green
eggs. These, along with the blues, can vary in tint and depth of color.
There is a bit of
debate over the differences of these colored eggs. Some people feel they taste
better, others think that they may have nutritional differences. I have yet to
see any scientific studies.
Yolk Color
The color of an
egg yolk should be very bright yellow or a deep orange. The difference in color
is based on what the chicken is eating. Chickens who only eat the grain feed
given to them will lay eggs that are yellow. Chickens that are free range and
eat mostly bugs and vegetation will produce these orange yolks. There may be
nutritional differences but I couldn't definitively tell you what they are.
Fertile or
Infertile?
Many people think
that you need a rooster for a hen to lay eggs. This just isn't so. In fact,
most of the eggs you buy at the grocery store (unless otherwise labelled) are
in fact infertile. If there's no reason for a commercial egg farmer to have
roosters they won't bother. Most of the hens producing eggs today will have
never seen a rooster in their life.
However, I know
some people buy their eggs from farmer's markets or directly from the farm. How
can you tell if those are fertile? It's really quite easy. Once you crack an
egg open look for a white spot on the yolk. If you can't see it use a spoon to
roll the yolk around until you can. If the white spot looks like a dot it is an
infertile egg. If the white spot looks more like a doughnut or bulls eye it is
fertile.
You may ask why you'd want a fertile egg. The answer is pretty simple. People who raise chickens often prefer raising their own instead of buying new chicks every couple of years so they keep a rooster around. However every egg is not going to be wanted for hatching, instead the extras are sold to be eaten. In the meanwhile the rooster will keep the hens happy and might even defend them from predators. Some people claim fertile eggs taste better. This appears to be a matter of opinion.

Does size mean
anything?
In the stores you
can usually find small, medium, large, and jumbo or extra large eggs. You might
wonder why this is. Some may speculate this has to do with breed but in the
commercial industry this usually has more to do with a hen's age. The older the
hen the more likely she is to produce these larger eggs. In fact some breeds
like the Rhode Island Red are so notorious for this that once they start
producing eggs too big for sale they're slaughtered for meat. The largest
chicken egg on record was over 7 ounces in weight!
As far as
backyard flocks go some of the smaller eggs are indeed from bantams. Bantams
are small breed chickens. They can lay just as many eggs as their larger
counterparts but they'll be considerably smaller. In fact I have some Seramas,
the smallest chicken breed in the world, and their eggs tend to be around 0.9oz
in weight, as compared to a normal large store bought egg which is 3oz. Bantam
eggs usually have much more yolk than white in them and are just as edible.
Many people prefer bantams simply due to their smaller space requirements.
How can you
tell if an egg is fresh?
It’s a bit
disturbing to know that some eggs are sitting on a shelf somewhere for up to
six weeks before someone buys them. So how can you tell if an egg is fresh?
Easy. If you put
an egg in a bowl of water and it sinks to the bottom and lays on its side than
it is as fresh as you can get it. If it sinks but stands on its end then it is
still fresh enough to eat but it is getting older. If it floats to the top of
the water its an old egg. Sadly most of the eggs I bought at the grocery store
were this way until I invested in my own laying hens. I can profess the fresher
the egg the tastier they are!
There are also
other ways to tell if an eggs is fresh. For instance if the shell seems
unusually thick than it is fresh. If the yolk stands really tall after you’ve
cracked the egg it is fresh. If the yolk has wrinkles or dissolves into a
puddle when you crack it open than it is an old egg.
Can you hatch
fertile eggs?
Yes and no.
Although you will sometimes see fertile eggs at your local health food store
they have been refrigerated and besides this they may also be old. Normally a
hen will lay an egg every other day (or sometimes every day) until she feels
she has enough eggs. At this point she'll go broody—meaning she'll start to lay
on the eggs instead of abandoning them as she's done in the past. Only then
will the eggs start to develop and after twenty one days all the chicks will
hatch out, despite being laid on different days. The problem with this is that
the older an egg is the less likely it is to hatch once its incubated. Most
breeders don't use eggs past ten days of age, although they can technically
hatch as old as three weeks of age, there just won't be as many. Before being
incubated the eggs must not freeze or get too cold, this will kill it before it
has a chance to start developing.
If you really want to hatch some eggs you're much better off buying "hatching eggs" from your local farmer or breeder. These will be fresh and kept at room temperature until they are ready to be used.

How many eggs
does one hen produce?
This is a loaded
question. Most of the breeds used in the commercial egg industry start laying
eggs when they are 4-5 months old. These breeds tend to lay an egg every other
day, sometimes an egg every day, but this doesn't last long. In fact when the
hen reaches two years of age her "peak productivity" will be lost and
unless she's someone's pet on a small farm she'll likely be slaughtered for
meat and replaced by a pullet (a hen under a year of age). If allowed to live
she'll still produce eggs, just not as many, until she becomes truly elderly at
which point she'll stop altogether, sometimes as young as three, sometimes as
old as five or more. Most hens generally live to be around five years old
although some have made it into their teens. Since no one is breeding
specifically for longer lived chickens this seems to be the result of pure
chance.
With all that
being said there are many breeds of chickens bred for all sorts of purposes.
Some are ornamental and win shows for their beauty, others are raised purely
for meat, while others may even be bred for cockfighting (which is illegal in
most of the US—not to mention cruel). These breeds of chickens may only lay
seasonally or they may just produce eggs sporadically. Instead of having up to
seven eggs a week you'll likely end up with 0-1.
