Hello everyone i am new to the forum and new to chicken farming. I am planning on raising some cornish rock chickens and i have some questions on the feed. What protein % or medicated or non medicated feed do i get them for when there chicks, then what is the next step of feed i should get them when they grow up, and when in the chickens age should i switch the feed from starter to grower feed. when do i give them grit and how much of it. Any help will be grateful and thanks very much.
