Not if I rake it out . . .
I had that tractor in the backyard at my old house, and NEVER moved it.
I had 6 standard-sized chickens in it.
I would just rake it out every once in a while as needed.
I am doing this in my backyard, and tho its pretty big, there is landscaping and its nowhere close to being a pasture, by any meaning of the word.
My layer coop is going to be "portable" ish, but I dont plan on moving that bohemuth too much either . . .
Us true backyarders gotta do what we gotta do . . .
Besides, tomoro they will be a week old(actually, prolly today) and since theyre going out on Saturday, thats only 6.5 weeks to be out there . . .
Edit:
To me its easier to rake out the tractor than to move it, I go to great lengths to keep my jack russell out of it, and it ends up being a semi-permanent structure.
I usually use 3' metal concrete stakes with screws to hold it down.
