So I was just sitting here looking at pictures on a few different threads and I found myself day dreaming about having birds running free on our land. We have 7 acres of land about half of it has dense woodland's the other half is pretty open with a few trees here and there which is where our house and coops are. There is a pond that the cattle use which is about 150 yards behind the coops. We are located in middle TN so our winters are fairly mild, with having an average winter temp of upper 40's but some night in the dead of winter it will get below zero F. So my question is, What would be the best poultry to have free roaming our land? They would have a shelter built for them if they wold like to get in it but I would not be locking them up at night so other than have a shelter to get away from rain and wind they would be completely wild. I would like for them to be able to sustain them selves nutritionally just off of bugs, grass and worms that they can find on their own. Of course I would not let them starve I would feed them if I saw it to be necessary! So what do you all think? What is the best poultry/breed that best fits these idealistics (is that a word lol) Thanks so much!!
