None of my local farm stores carry feed especially for chicks in that "in-between" stage. They only have chick starter (always medicated, non-medicated is rarely available) and meat bird feed ("flock raiser") or layer feed. There is nothing with the right protein amount that doesn't also have lots of calcium for laying. I have raised plenty of chicks going from medicated feed up to 6 weeks, then Layer feed after that, but I've heard this can cause kidney problems. I also do not have much way to isolate the feeding of pullets from the adults. My flock is free-range so they do get a large portion of "wild" feed.. My farm & home store says the closest they can come is Purina's meat bird feed. Any suggestions?
