I want to know the answer to the following question:
How has breeding helped in the pultry industry?
All the background I'm provided with is that "In about 1800, chickens began to be kept on a larger scale, and modern high-output poultry farms were present in the United Kingdom from around 1920 and became established in the United States soon after the Second World War.". Is that enough to answer the question?
Answer: no
