In the United States, CAFO egg-laying operations can have as many as 6 million chickens. In Canada, the average is 25,000

 

Which is why egg prices are stable in Canada.

From The Poultry Site:

In-line egg operations are characterized by an automated egg collection system that carries eggs directly from chicken houses to the egg processing plant (building). These farms produce, process, pack, and ship eggs at one location. Large commercial “in-line” farms containing 50,000 to 6 million laying hens produce over 85% of table eggs in the United States. 

Sonia Aslam writes in City News Everywhere: 

“Laying hens catch it very, very easily. They don’t have the same sort of even remote resistance to avian influenza that wild birds might have. They have about 300 million laying hens in the U.S., but over the last three years, probably half of that number have had to be euthanized because of avian influenza.” 

Muirhead points out that in Canada the average egg farm is about 25,000 birds. [emphasis added]
