I'm is a tough spot right now because I can either feed my mixed flock layer feed (including the eight-week-olds--which I know is not the best idea) or I can feed them medicated chick feed. My local feed store doesn't have anything else except grain and scratch. Will the medicated feed be a problem for the layers? The past few days I've fed everyone layer because I can't keep the adults out of the chick feed. I'll be going out of town next weekend and can hopefully find some non-medicated grower somewhere else, but I'm not holding my breath at the moment. Any suggestions?
