In reading the forum, it appears that laying chickens need more protein than baby chicks. I am starting to get confused. I started my chicks off on Purina SunFresh, and it says An 18%-protein ration perfect for raising laying chicks from hatch to laying age (18-20 weeks). The 2nd time I purchased feed, they were out of the Purina, so I got HomeGrown Starter/Grower 18%. When I read the Purina website, it says to switch to their Layena SunFresh at 18 weeks: A 16%-protein high-calcium ration formulated for top-producing laying birds once they reach 18 weeks of age. Why is the protein % less in the layers' feed than in the growers' feed? I thought it would be just the opposite. Or am I totally confused by how much protein is needed by chicks & layers?
