# CAL-MAINE FOODS
REPORTS SECOND QUARTER 2006 RESULTS

JACKSON, Miss. (December 28, 2005)
 Cal-Maine Foods, Inc. (NASDAQ/NM:CALM) today reported results for the second
quarter and six months ended November 26, 2005.

Net
sales for the second quarter of fiscal 2006 were $138.3 million compared with net sales of
$90.7 million for the same quarter of fiscal 2005. The Company reported a net loss of
$685,000, or $0.03 per basic share, for the second quarter of fiscal 2006 compared with a
net loss of $5.3 million, or $0.23 per basic share, for the second quarter of fiscal
2005.

For
the first six months of fiscal 2006, net sales were $218.0 million compared with net sales
of $192.7 million for the prior-year period. The Company reported a net loss of
$8.8 million, or $0.37 per basic share, for the first half of fiscal 2006 compared
with a net loss of $6.2 million, or $0.26 per basic share, for the year-earlier
period.

Fred
Adams, Jr., chairman and chief executive officer of Cal-Maine Foods, Inc., stated,
All of the Cal-Maine operations ran smoothly during the second quarter. This was the
first quarter to consolidate the operations of Hillandale LLC with Cal-Maines. The
assimilation has gone well, and we are confident that we will generate more savings and
synergies in the months ahead.

Egg
demand, sales volume, and egg prices started slow in the second quarter but finished on a
very strong note, with robust sales and improved egg prices during the three weeks leading
up to Thanksgiving. Following Thanksgiving and continuing until Christmas, egg demand has
been excellent, resulting in higher egg prices. Cold, snowy weather in much of the country
added to strong seasonal holiday demand.

Corn
and soybean crops were both large, and our feed costs are projected to be favorable in the
months ahead, Adams added.

Cal-Maine
Foods, Inc. is primarily engaged in the production, grading, packing and sale of fresh
shell eggs. The Company, which is headquartered in Jackson, Mississippi, currently is the
largest producer and distributor of fresh shell eggs in the United States and sells the
majority of its shell eggs in approximately 28 states across the southwestern,
southeastern, mid-western and mid-Atlantic regions of the United States.
