Friend of mine works with a chicken plant in Kentucky. He posted these pics on another forum. They hatch 3,000,000 chicks a week there.

Egg Holding Room



Computerized Candle...Removes All Non-fertile Eggs



Inovoject, Vaccinates the Chicks at 19 Days of Incubation, While Still in the Shell



A View of a Hatchery Hall, Each Machine Holds 15,000 Eggs



A Chickmaster Incubator, Each One Has 100,000 Eggs



Chicks Headed to the Computerized Counters



A Chick Counter Counts +/- 3 Chicks Per 1000, at 60,000 Per Hour



Complete Computer Driven Load Out...Matches Chick Numbers to House Size, ect.
