Still in the planning stages here, and trying to decide on a number of things. What is the largest tractor (coop, enclosed run) that I would be able to move on my own. Would something suitable for 8 chickens be out of the question? I'm not worried about my wife (don't know all the abbreviations ) being able to move it because she said this will be my thing (although I think they will grow on her). Thanks again guys!!
