It might be the feed. They need enough protein to lay. Also stress and length of daylight will affect production

The most rational choice, given that it is area wide thing, is aliens/zombies/or DOLLYWOOD.

Order a water test kit and test your water, from the hose you use to water them. I had this problem last Spring--my quail, ducks, and chickens had stopped laying for months and months and months. Turns out, the hose was leaching plastic chemicals into the water that happen to have been shown to suppress laying in wild mallards.

I put a carbon filter on the outdoor hose, and a month later they started laying again.

If it's the whole neighborhood, could be a neighborhood water quality problem, and best to get it checked into asap. No water test kit will tell you everything about the water, and if it's the whole neighborhood you may be able to get the city to check it for you. Good luck!

P.S. That or alien abductions.

Lack of daylight hours aside the most common causes is stress, disease, parasites, broodiness or incorrect feeding. It's unlikely that your chickens and the other people in the area's chickens all affected by one or more of the above at the same time. I'm leaning towards an egg thief. Are your coops predator proof? As in mouse and small animal proof?

Egg thieves come in many shapes and forms, birds, snakes, rats... Check all boundries of your pen and if that fails you could also try offering a new (more protected) laying box.

Note mice/rats/snakes are capable of using very small entry points limited only by the size of their skull as I understand it. Throw in a fake egg, if it dissapears you know its a thief.
