Irvine’s grandparent farms are situated in the Harare South area. Cobb grandparent chicks are imported from Cobb UK and reared under strict environmental and bio-security controls. Twenty seven weeks later, the birds start laying hatching eggs which are transferred to the parent hatchery where they hatch into Cobb parent day old chicks. The increase in production of parent day old chicks has seen Irvine’s Zimbabwe penetrate into regional markets with over 50% market share in a number of countries. The Cobb parents will start to hatch at about 27 weeks. Some hatching eggs are sold to local and regional hatcheries for production of chicks only after satisfaction of the local day old chick requirements. Majorty of the hatching eggs are transferred to the Commercial hatchery for hatching of broiler day old chicks.
