this will be the 3rd different feed that my 5 week old chicks will be eating. weeks 1-2: Nutrena medicated chick starter/grower 25# weeks 3-5: Nutrena Gamebird crumbles 50# week 6.....? Now i need to buy more feed but the store i normally go to is already closed by the time i get home from work and the only place around me that will be open after 5pm is Agway and they don't carry Nutrena. the have the Agway chick grower which has 14.5% protien. i'm not sure about the % in the nutrena feed because the gamebird crumbles bag never had the tag w/the ingredients on it but i'm assuming the protien was somewhere around 20% give or take. Is it wise to switch to a feed with a lower protien content?
