I don't show on that large of a scale, i.e. I don't show at national shows, only state and county shows, so i feed my chickens purina start and grow and then later on purina layena. Im just curious what people who are really into showing feed. I have heard people using manna pro showbird feed. The problem with that is my show girls are my layers too, for the next year, so I need to make sure they are laying. What do you guys feed your show chickens?
