The Cobb 500 is a fast-growing broiler chicken breed. They can reach a 2 kg slaughter weight at 33 days old.

Cobb 500 and Ross 308 are both popular broiler chicken breeds, each with its own strengths. Cobb 500 is known for its rapid growth rate, high feed conversion efficiency, and suitability for whole bird markets. Ross 308 is favored for its high breast meat yield, robust performance, and ability to thrive under less controlled conditions.
If you prioritize maximizing breast meat yield and need a breed that can handle less than ideal conditions, Ross 308 might be a better choice.

If you need a breed that grows quickly, has good overall meat yield, and is suitable for whole bird markets, Cobb 500 could be a better option.
