LOL you won't do it right, at least not everything, until you've done it (does that make sense??). Because no one can tell you what's right for you. Ignore everyone who doesn't fit what you see for yourself, and listen to the advice that makes sense to you, and learn as you go. There is no other way. And this is coming from someone who researched and read and asked for two years+ before ordering her first chicken. Keep asking and learning, but just come to terms with the fact that there is no way to insure you will do it right the first time.
Here are my experiences- don't listen to anyone who says that you can't free range and that you'll just be fattening up the birds for predators. That's crap. People free range all the time, all over this country. I live in central MN where we have every type of predator- well, no mink or otters where I live because we're not close enough to water, but everything else, especially an active raptor population. I've been free ranging my birds for almost a year and my only loss was INSIDE my run, when an older chick was carried off by a hawk (I assume- there was no trace left behind). That is, however, another reason to get a good heritage bird that is PROPERLY CAMOUFLAGED (something no one has brought up yet...) for your area. I'm thinking it is yet another reason to go with Delawares or possibly even a more colored bird, like barred rocks or buckeyes, that well blend in well in a wooded area. Plus heritage breeds generally have better instincts when it comes to hiding and fleeing. And you could always get a goose- I hear they make good predator defense. But there are ways. It's just a matter of solving problems as they occur.
I think the median approach would be this- buy a small flock (whatever seems reasonable to you, just remember to assume about 1/2 will be males, and you'll want to cull all but one or two males before winter to prevent fighting, so get about twice as many as you plan to keep over winter) of heritage from a reputable breeder, and buy 10 or 15 colored broilers/rangers from a hatchery. That way you would have meat this year, while eventually developing a self sustaining heritage breed to eat in the future. Colored broilers will still eat a lot of feed, but range more and have chicken instincts left, so will hide from danger. Only problem- minimum order is usually 25, but you could split an order, or add another breed of chick, or whatever you think.
Whatever you do, don't consider cornish X for your situation. I've never heard of anyone being able to free range cornish cross unless they were raised under a broody hen, and given my experience with them I can see why- they are fat, lazy, don't clean themselves, and have no chicken instincts.
Hope you're able to find some help in all of this advice, from me and everyone else!
