No X-Large eggs?

I've always bought X-large eggs.  Last week, Publix did not have any. Did not think much of it, stiff happens.
Saturday, I was talking with a friends in Massachusetts. She mentioned that for a couple of weeks, should could not find x-large eggs.
This morning, I want to BJs.  They have  a few varieties and packages. You can get Cage Free, Captured and tortured, organic, and more.
But no X-large.  I know millions of chickens were killed from bird flu, maybe the replacements have not grown enough to produce the larger eggs?
