I'd imagine free ranging your birds isn't so practical in the wintertime. I've got a barn where I imagine the birds would be content staying inside in bitter cold, but I could be wrong and I'm sure they'll make their preferences known. If the weather is cold enough to keep them indoors, and therefore always eating feed, do I want to raise crickets or worms to supplement their diet? Do I want to bring them some other meat products for treats? Daily? A few times a week, several times a amonth?
