Commercial Day-Old Broilers (Cobb 500) Our day old chicks are produced under high bio-security, hygienic environment and from high-quality parents. We also ensure they are adequately vaccinated for their age. The Cobb 500 broiler strain offers feed efficiency and yields for live market/poultry meat processing production. Its comparably higher processed/breast meat makes it a preferable choice for poultry producers. The price listed is for a carton of 50 chicks.
