Mystery Solved

 For about a week I wasn't finding any eggs in the coop in the morning. It was getting to the point that I thought I'd need to buy some from the store (gasp!) We use a lot of eggs here, and with only three hens we need every last egg. A broken shell is a minor tragedy. I was starting to assume the hens were eating their eggs for whatever reason chickens do, when I saw an egg in the middle of the yard--just sitting there. After I picked it up I figured I'd go on an egg hunt. Peeking behind an old pallet we propped up for shade, I found a HUGE nest with nearly a dozen eggs in it. All the eggs passed the float test, and now I know where they're being hidden.

Naughty chickens think they can hide from me!
