This is our first year raising layers and our first year wintering them over. I have a question about scratch feed - what's best to use and in what quantity? We have all cold-weather-hardy girls (Red Stars, Australorps, Buff Orpingtons, Silver-laced Wyandottes, Jersey Giants, Speckled Sussex, Barred Rocks) and live in Western New York. Right now we're feeding layer feed and oyster shell; they are free range, too, so at this point they're supplementing their diet with whatever else they want/need. We will be closing them up in their coop for the winter, though, and only letting them out on the nicest of nice days.
