Every once in awhile the chickens will get a wild hair (feather?) up their butt and decide that The Coop Is No Longer Desirable. Sometimes it's the presence of a broody hen, yelling at any other hens daring to approach her precious clutch. Other times they've figured out that their Eggs Are Disappearing, and that's not good. Whatever the reason, once they decide The Coop Is No Longer Desirable, they'll hie off to some hidden, cozy location on the property to start laying eggs anew.
This is the third time in two years I've had to do an egg hunt. None of those times have fallen on Easter, just so you know.
The current egg diaspora is due to Blondie #2, aka Specklebutt, who has been broody for several weeks. She has an egg that is close to hatching, and is being a royal scold to the other hens. "Screw this!", you can almost see the girls harrumph, "I'm going elsewhere!" This time "elsewhere" was behind two outdoor trashcans that are up against a cutaway on the backyard hill. Nice bed of oak leaves, too. They'd actually two different "wild" clutches going. The first one was found relatively quickly, and some eggs were appearing once more in the coop, but not at the same volume as before. This second one took over two weeks to find.
Once a clutch-in-the-wild is found, the hens (usually) go back to laying in the coop again. Crossing my fingers that they all finally do so. Crafty chickens!
