I love that idea!I feed them 20% protein flock raiser year round. The only thing I do differently in the winter is what Sally described - I make them a mash out of their regular feed, but with hot water (either the fines, or the crumble if there are no fines currently).
Ironically, my chickens only get to graze on grass in the winter. I don’t free range and they aren’t allowed in the garden during the growing season, but I plant winter wheat in it in the fall, and it stays fresh and green all winter. That’s when I let the chickens into the garden (it’s fenced and covered on top so they’re safe in there). In the warm months, I give them glass clippings from mowing, branches from shrubs they like, etc. so they still get greens, but it’s only in winter that they get to walk on grass and pick it themselves. Which is funny because winter in Boston is cold and dead, and among the snow there’s this oasis of green, with chickens in it![]()
