The incredible shrinking eggs? What\'s up?

[Providence Hill]

My daughter has been getting some lovely blue eggs from her little flock of bantam wheaten & black pullets, but today she found something that looked just exactly like a robin\'s egg.  Even stranger, yesterday she also found a very small egg, although not as small as today\'s.  In the photo (sorry it\'s blurry) you can see one of her normal eggs, followed by yesterday\'s, followed by today\'s (with a dime for reference).  What\'s going on?  Will whoever is laying these eggs go back to laying normal ones again?  This is their first spring laying, if that makes a difference.  Sorry I couldn\'t capture the color, they really are a very pretty blue.  She wants to save the tiny one, but I\'m not sure I can blow out an egg that small without crushing it!

\"Peanut eggs\" are not that unusual.   I\'m not sure what causes them, but usually the eggs from that hen will return to normal after they take a break from the laying cycle.

Oh good!  Although it was charming to find one so small.  The kids thought a robin had somehow gotten into the coop.

That\'s an egg fart.

That\'s an egg fart.  

LOL that is what I call them to.

I have also heard them called fart eggs unstead of an egg fart but my grandma always called them a starter egg which I think sounds better.  Anyway, you don\'t have to blow it out, it will dry out on its own. Just put it in a safe place where it gets air and it will dry out on its own in time.

I have about seven of these drying out.  I sniff them occasionally to make sure they don\'t blow up in my kitchen cabinet.

They are caused by tissue flakeing off.The body then adds egg white and a shell just as if it were a real egg but smaller since the piece of tissue is small.
