The Egg Eating Chicken

A few weeks back, I noticed our egg production down, and wondered what was up.

While I was in the barn awaiting Misty's birth (goat), a few chickens got back into the barn into the coop.  I heard some loud squawks and looked over.  Lo' and behold, the no-name black araucana was chasing a barred rock around.  Then I saw her bully two barred rocks from the roosts, and put her head into the roost.  

I was certain I had my very first case of an egg eating chicken.  I put her in the emergency (just a small spare one for sick/injured chickens) coop for over a week.  I noticed egg shells in her coop on some days and others not one egg.  While in the other coop, I would get 11 or more eggs.
