Our chicks are 5 weeks old and have been raised to this age on Purina Start-N-Grow. Yesterday I went to our local feed store to buy more feed and asked for starter feed for baby chicks. I paid for it and they loaded it into the trunk of my car. When I got home and looked at the bag, it's not labelled as chick starter feed. The label isn't very informative. It's made by Nutrena which is the line of feeds this store carries and is called simply "Premium Poultry Feed". I went online to the Nutrena website and it's not very informative either. The "Poultry Feed" is described as "complete nutrient formulation to allow use of a single feed." Nutrena also makes "Chick Starter/Grower" which is what I think I should have bought. Nutrena also makes "Poultry Grower/Finisher" , described as "Nutritionally balanced to match the nutrient requirements of growing birds...". I'm very confused as to which feed is right for my 5 week old chickens. Can I feed them what I bought or should I go back to the store for a different kind?
