I don't do a lot of fancy additives but To every 50 pound bag of of Layer crumbles I add/mix in 2 cups of old fashioned oatmeal flakes and 2 cups of black oil sunflower seeds "SHELLED" While I was feeding the rabbits and noticed the deep green color of the feed and thought that it surley contained some good nutrients that may be of value to my silkies diet. My birds love to eat grass spring/summer/fall And get no access to grass in this cold Northern Winter. So I want to add 2 cups of the pellets to the50 pounds of layer crumbles as well. DO ANY OF YOU GIVE YOUR CHICKENS BUNNY PELLETS???
