Thanks, guys! That's very helpful. I know Salatin's chicken tractor dimensions are huge, and in every picture of them, they are on FLAT land. That's not the case here in northeast Georgia, in the foothills of the Appalachians. I think a smaller tractor on wheels will serve me well! :D
I'm about to jump into a more intensive year of raising cornish x on pasture, and want the best design for a chicken tractor. I have the book "Pastured Poultry Profits" by Joel Salatin (my hero!), and it seems like he has it down pretty well. Does any one else have any tips or tricks? Thanks!
