Product demand, particularly among the urban populace, is the primary reason for the growth. According to NECC Chairman P. Selvaraj, area egg consumption over the last five years has grown by 6% or 7% annually. Namakkal is already the second-largest egg producer of more than 30 zones mapped out by the committee.
As of March 2011, the Namakkal Zone had 45.9 million laying hens, with Namakkal itself accounting for 80% of the birds. Area expansion includes adding 4 million hens to the flock, with 3.8 million (95% of the total expansion) residing in Namakkal.
