Itty Bitty Egg!

Look what I found this morning!

An itty bitty egg!!!

I’m not sure why it is so much smaller than the regular eggs, it comes from the same chicken.  This doesn’t happen all the time (every couple of months or so).  I’ve cracked it open and the yolk is not developed properly and the white is very thick.

Does anyone know why my chicken would be laying these cute little things?  I’d love for someone to tell me!
