What's in an eggshell??

Well apparently a LOT!  While making breakfast for Tara and Madeline earlier this week, something, well, different caught my eye.  One of our Henny Penny's lays very light colored eggs.  I never really thought much about it, that was until this week.  Here is what her "cracked" shell looks like next to one of her sisters eggs.

See how pale her egg is?  It has little brown speckles on the bottom as you can see.  Sometimes they aren't speckled, but this one was.   Now look here at the inside of her sister egg. . .

See how it's white in there?  Well, all brown egg laying chickens have white eggs, and the color is applied in the very last stage of egg travel before it's laid.  Which means that all brown eggs have white insides.  This is not true however for blue egg layers which lay eggs blue inside and out.  There is an actual science behind this, which is clearly explained here.  The article says " It takes about 26 hours for an egg to go from the ovary until it is laid. First the yolk is encircled with whites and membranes. Then this jelly-like mass goes into the shell gland, where it will spend about 20 hours while the shell is formed.

The shell is made up almost entirely of calcium carbonate, which is a white mineral. White eggs are white, through and through. But, during the last four to six hours in the shell gland, a brown egg-laying hen adds pigment to the mix. This is why the insides of brown eggs are white – the egg starts out white, and gradually becomes more colorful. In the last 90 minutes, the rate of shell formation slows, and the cuticle, a viscous, protein-rich fluid (also called the bloom) is added. (The cuticle is the first line of protection against bacterial infection in the egg.) This is also when the hen secretes most of the pigments into the shell."

So what do you think happened here??

How on earth did she get the color on the INSIDE??!!

And which of you girls is the amazing magician who performed this magic trick??!!
