I am on my last feeder fill of Developer. I have 4 1/2 week old BR and 6 wk old EE's and BO's. I went to the other feed store in town and they sell Nutrena that goes right to "layer" feed after "starter" feed. I bought one bag to get by. The store can order a non medicated 16% feed, but they don't have it in stock. Am I good to go w/ the layer feed or should I have him order the other?
