Free Ranging
Human raised chicks vs flock raised chicks .The latter are the smartest.Just wanted to share my experience today that is unfortunately relevant here as far as hazards of free ranging. It's not just predators that are a risk - chickens can do a runner for other reasons. I have read more than one account of frightened chickens just running off into the forest never to be seen again, presumably either getting eaten eventually or just getting lost and going elsewhere.
I have 6 pullets, which is not safe to properly free range since they're little derps and definitely don't watch for hawks. Instead, I have been letting my birds out closely supervised for a half hour here and there, and thought they knew how to run back in the coop if they got scared as they've done this many times to date when scary things happened or when I've spotted something and herded them back. This morning, there was a really loud nose caused by a chicken knocking something over, and they just ran outwards in all different directions and kept going. Utter chaos in an instant and then trying to catch birds before they completely left the clearing for the forest. Got 5 out of 6 back but the 6th was missing without a trace. Hawks in the area heard the commotion and immediately moved in to fly low and look for snacks. After a lot of walking in the forest and an incredible amount of dumb luck, I found my chicken hiding under the branches of a fallen tree. She was silent and well hidden, so at least she had good instincts on where to hide for safety, but the odds...I found her after I'd given up and was heading back. I was not prepared for the hit of suddenly knowing I had to beat every predator in the area to finding a lone chicken in 20+ acres of forest. I don't think I can rely on the same degree of luck in the future, so I immediately ordered a large run extension kit and that will be it for letting my chickens run around out in the open (at least until I have a rooster to help me out).
I'm guessing if you're away from the forest it may be less of a risk of what I just experienced. It's so much harder to chase a bird through forest than grass. People nearby free range and don't lose birds as far as I've seen, but they do so from much bigger cleared areas with just a tree and shrub here and there. They also have older birds and most have roosters with them. My impression is a small group of hens is just not very safe on its own.
