What type of feed have you found to be the best/healthiest for your birds? I'm new to this and I want to make sure I know what things need to be in the feed for the best success. I don't necessarily mean a brand, but what type with what ingredients are the healthiest/ best for chickens that will be dual purpose birds? I want to make sure I am feeding my birds good stuff... because that's half the reason we want them, so we know what they are eating, and that they are eating better than the birds you'd buy in the store. We are willing to pay a little more for the good stuff! Thanks!
