Detective Chicken-Catch-A-Story Cracks the Case

Detective Chicken-Catch-A-Story is called to her first case. The Eco-Friendly Farmer's hen house is producing soft egg shells. What is the cause? How can it be fixed before the County Fair? The eggs are very important. The Eco-Friendly Farmer must feed lots of people. The Farmer's Wife needs eggs for the baking competition at the fair.

And what is the Farmer's Daughter up to? Perhaps a lesson in honesty.
