Why are egg prices rising right now?

Egg prices move for structural reasons that repeat every cycle, and they move faster than almost any other grocery staple: an egg is laid, graded and sold within days, there is no meaningful import valve, and the laying flock that produces every egg takes months to expand. When supply tightens, the price does most of the adjusting.

Bird flu is the defining shock. A single HPAI detection in a commercial layer flock removes the entire flock, often millions of birds at once, and a replacement flock takes roughly five to six months to reach full lay. That is why an outbreak moves the benchmark for a season, not a news cycle. The HPAI layer-flock tracker follows every detection, and the US egg production page shows what the national flock has done to output.

The flock is the supply base everything else plays out against. Even without an outbreak, a flock running below its historical size means fewer eggs per day against steady demand, and the market firms. Hatchery decisions made months ago set today's supply, which is why egg prices can stay elevated long after the headline event has passed.

Inventories are the short-run buffer. Wholesale eggs held in warehouses cushion week-to-week swings, and when shell egg inventories run thin for the time of year the market reads it as a shrinking cushion and firms ahead of any visible shortage.

Demand has a real calendar. The holiday baking season from October through December is the year's peak pull, with a second seasonal lift into Easter, so the same supply squeeze bites hardest in exactly the months demand crests. A price rising into November is partly the calendar doing what it always does.

Feed and production costs set the floor. Corn and soybean meal are the biggest cash costs of keeping a layer, and a sustained feed rally raises the cost of every dozen; producers cannot absorb it indefinitely, and the wholesale price eventually carries it.

The retail shelf follows wholesale with a lag, and cushions it. Grocers smooth wholesale swings, so the retail average price typically rises later and less than the benchmark this page tracks; a wholesale spike is the leading edge, not the checkout price, and the price history page shows how past spikes played through.

None of these act alone. A rising stretch is usually a supply shock leading, with the flock, inventories, feed costs and the demand calendar deciding how far it carries. The falling twin of this page covers the same factors running in reverse.
