This morning it was minus 11 as the sun was coming up. For breakfast and later lunch my Americauna chickens had mashed potatoes in addition to their corn/peas/sunflower seed mix. I grew over 500 pounds of potatoes and 400 pounds of winter squash last summer, more than I need but the chickens will certainly benefit. I think that giving them cooked food like potatoes and winter squash is more than a treat. Although low in protein the fresh food has plenty of nutrients not in their grain mix plus it supplies them with much needed water in the winter. They really enjoy the cooked food.
