How Can I Get My Chicken To Lay Bigger Eggs?

It's mid-Spring now in most parts of the country, and last year's chicks are really getting into the swing of laying eggs!  (This year's chicks are still being raised, and will start laying around July or August.)  A common question I hear this time of year is, why are my chicken's eggs so small?

The first thing is to distinguish between "regular eggs that are just a bit on the small side compared to supermarket eggs," and "this bizarrely tiny egg without a yolk, about the size of a quarter."  The later are politely called "wind eggs," or more colorfully known as "fart eggs."

(I have illustrated this post with a picture of three regular eggs and one fart egg.  For illustration purposes, and also because it's pretty funny.  When I cracked open the fart egg, inside it was just egg white that was cloudy.  This is normal.)

Next, we have to determine what size your eggs really are.  The USDA egg grading manual averages weights over a dozen.  Per egg, the average minimum weight is:

Large:
56 grams
Extra Large: 63 grams
Jumbo: 70 grams

Be sure to actually WEIGH your eggs before you start to worry.  Your eggs will probably be physically smaller than grocery store eggs.  But because the egg shell of a backyard chicken's egg is so much thicker, it will weigh more proportionately for a smaller egg.

I recently had occasion to crack a regular grocery store egg.  I was shocked at how much larger it was than my own chickens' eggs, even though technically they are the same weight.  And then I was shocked at how thin the eggshell was!  And the yolk just looked pale and sad.

The grocery store experience tends to skew our expectations.  Eggs come in all different sizes, and the "average" egg is a Large (56-62 grams).  Even though we think of Extra Large or Jumbo as a "regular" egg, these are actually pretty big eggs.  

Assuming that your chickens are getting enough fresh water and feed, there are several factors involved in the size of your eggs:

The Hen's Age

A pullet or a young hen will start out by laying eggs on the small size.  The eggs will get bigger as she gets older.  As a rule of thumb, the older a hen gets, the fewer, larger eggs she will lay.

Genetics
Some breeds just lay larger eggs than others.  Even within a breed, the variation between hens can be significant.  Larger hens tend to lay larger eggs.  Leghorns are generally accepted as laying the largest eggs, which is why most commercial egg production hens are a Leghorn cross.

Protein

Protein is the biggest nutritional factor in egg size.  You can try blending some feed meant for meat birds (like Purina's Flock Raiser, 20% protein) in with your layer ration, to increase the overall protein percentage.  However, it seems that increasing protein only increases the size of eggs for the first few months the hen is laying.

Above all, remember that quality is better than quantity!  Even if your chickens' eggs are a little small, they are still FAR better than those freakishly big eggs you can buy at the store.

I have never heard this term before. My Family has always referred to the smaller no yolk egg as a "Second Egg" the second egg is simply the albumen left over from the previous egg. Calling it a fart egg seems to me and my chicken pals, to degrade them and make the person saying it seem vulgar and uneducated. I do hope that people will stop using the term because Chickens are such Glorious and regal creatures in thier own right.

Dear Chicken Queen,

For the love of God, please lighten up.  It never ceases to amaze me how some people can take offense to benign comments such as this.  Seriously, I didn't think that it was possible to "degrade" or insult an egg.  Not only that, but you chose to call the author of the article "vulgar and uneducated."  Seriously, get a grip and don't let your panties get in a bunch over innocent comments.
