I have my own small flock of backyard chickens and they naturally lay less in winter. In fact I had to buy a dozen eggs for the first time in a long time last week. It only takes a couple percent change in an inelastic demand to push prices up a lot.Eggs historically have gone up in price as Easter nears compounded by a bird flu which has been in the news. The prices are still much cheaper than they were a couple years back.
