10x20.........a hoop coop/tractor when assembled is roughly 8' wide. Pretty close to the 10' desired. Building the base out of 2x6 or 2x8 lumber would make it pretty darn strong.
How many birds are you planning in each tractor? You may not need to move them every day if your bird density is not heavy. They would need drug with a tractor or riding mower or atv at 10x20 in size. Maybe that mower, tractor or ATV could be used to knock down tall grass in section it is getting moved to. That should make it take just a few minutes.
