I have always been told that feeding grains to chickens raises their body temperature. So I've always been mindful of giving more scratch in the cold months and less during the hot months. How many of you follow this same rule of thumb? I read a blog tonight that said they had taken to giving oats to their chickens with their feed and it increases egg production but they didn't know why. Then I realized it was an old blog post written during cold winter weather. For the warm months I like to make homemade yogurt and freeze it in ice cube trays (you have to spray them with cooking spray first) and give the frozen cubes to the chickens for a treat. How careful should we be with grains in hot weather? Or does it really matter so much and it's ok to continue grains throughout the warm months?
