Hi, I'm interested in having a small sustainable farm and having chickens is at the top of my list. I would like a chicken that needs little-to-no management and can graze in the pasture. I would like eggs and some meat too. Perhaps I'll need to have two different breeds to accomplish that but if one breed could be a happy balance between the two that would be good. I would like something hardy that can stand the Texas weather and is not susceptible to disease etc. I'm willing to trade off on egg and meat production for a bird that can meet those more important criteria. I'm totally new to this so I really am starting at ground zero. What suggestions do you guys have for me?
