If your coop is 4-8' wide then you will probably find that is easier to do a one time move by slipping a piece of plywood under it and sliding it to where you want it. You can drill holes in the leading edge to pass ropes thru to pull on. The plywood won't sink into the dirt(lawn) like a wheel but will still slide over hard surfaces. (A thin leyer of sand will help here) If one sheet of plywood isn't big enough, then use two. After the coop is moved you then have material to start on a second coop....
