I use Buff Hooligans' "Treats Chart" found on her website regularly. An excellent resource, if you haven't use it yet. Here's a link: https://www.backyardchickens.com/web/viewblog.php?id=2593-Treats_Chart I have been bringing my BOs and GLWs a treat of warm oatmeal with grapes and raisins mixed in on quite a few of the really cold days we've had lately. They seem to be getting tired of it. More and more of it is left over and frozen when I check on them. They used to literally ATTACK it when I first started bringing it to them. Maybe they're getting finicky? What other warm treats do you all give your chickens on cold days?
