This will be my first winter with chickens. There gonna freak out when the grasshoppers go away. I'm in the process of putting my fall garden in. I read about growing kale for the chickens. I'm gonna grow some but was wondering, How much do I grow? I have 10 birds. I've fed them lettuce from time to time but seems they like grass more. Maybe they will eat more lettuce when the grass dies. I 'm assuming they will eat mustard greens & everything I plant for the fall. If not their gonna be stuck eating pellets. Which is something they really only snack on.
