Okay, so DH and I were in Elijay, Ga last week and I saw the craziest set up. It was these individual blue, upside down, pail-like coops placed in rows out in a field. From the road passing by, it looked like there was a rooster/hen chained to each coop. Is this a style of chicken raising? Why would they house them that way? Are those 'free ranging-like' birds?
