Hello, my name's Jake and I'm from Oregon. I've raised chickens before, but never done free range. My brother and I are wanting to start an egg buisness, we're wanting to start with 100 Gold Sex Links and 100 Rhode Island Reds. We've decided that we want to do free range, but givin that that we've never done it, I need to know about feed. I've seen some people just spread out meal worms to make sure they have food, but would that be enough? Do I still give them feed? If so, how much? Thank you in advance!
. Great to have you with us! Wow! You are starting out large scale! Actually, laying hens need a balanced layer ration. Free ranging supplements this with insects, seeds, and greenery, but for the hens to lay consistently and to keep egg quality high they will still need the aforementioned layer ration. Laying hens won't overeat so if they have free choice feed and their ranging you will be all set. As you are starting with a jumbo sized flock, you might check out the Learning Center here 
. Also 200 birds will quickly exhaust whatever was available on their range and you'd have hungry birds. If you have a grain elevator or animal feed plant near you they can likely make you a layer ration. With that many birds, bulk feed is the only way to go! Again...best of luck!
