I haven't heard anything, one way or the other, about nuts. It never occured to give them to our girls because we have plenty of leftovers and fruit/vegetable scraps they can have for their 4:00 snack. I knocked over a jar of roasted pecans and they fell to the dirty floor and I scooped them up for the chickens. They had their first snack of nuts today. They loved them. Is it ok to give them nuts on occasion? Bok.
