Most farms are pretty small by me. I live in an agricultural area, but not out west. The big crop here is chickens too. Any field crops tend to be focused on supplying the chicken industry too. So we grow either feed corn, or soybeans. With a little wheat, and rye tossed in. A few folks try to farm some strange stuff though. Once I was driving up a road and I could swear I saw a flock of emu. There's a bison farm here too. I get a kick seeing those. The chicken business is pretty cut throat I've heard. So I imagine most would like to avoid it, if they can.
On the talk radio here there was this one zany local that used to carry on about lawns. He was a hoot. Your comment made me think about him.
What the little farms here do is they hire out the harvesting to bigger outfits that have the combines, and harvesting equipment. Because that equipment is quite an investment to have. So the crews go around field, to field when it is harvest season, and harvest everything that way. I think they might share some of the other specialized equipment too. Like the tall field sprayers, and stuff like that.
