Half an acre or so?
Seriously, something on that order. Ask Davaroo, he always has numbers handy
Chickens just really
do make a mess of the ground, what with eating, scratching, digging holes, compacting the soil, and poo-poisoning the soil.
However, they do this in a tractor too. Realize that you will be leaving a trail of *half*-bare, pooey, *somewhat* scratched and dusting-hole-d up lawn behind the tractor as it goes along. They are no no-impact IME, they just distribute the impact over a larger area.
Also it is pretty difficult to construct a strongly predatorproof, easily winterized 10-12 chicken tractor (the ones used for broilers are not so appropriate for year-round layer use, and also may not suit your aesthetics). If you have something mechanized to pull it, and a very flat lawn, it'd be easier. Best bet would be to make the coop part and the pen part separate, so you move them individually then hook back together.
I prefer a permanent coop just because of electricity and more permanent fixtures.
I think there is a lot to be said for that. And you need not be depriving the chickens of bugs and green stuff to eat -- you can chuck in all sorts of garden weedings (not the few poisonous things) and over-the-hill veggies and kitchen scraps and so forth, and they will have a grand old time, *in the run*.
I also want the advantages of free range and lower feed cost.
If you feed them weedings and extra veggies and kitchen scraps, you will have the same lower feed costs (probably better, unless your yard is quite large) *and* won't be losing them to hawks etc like you sometimes will free-range. Oh, and if you have a garden (either flower or veggie) where you care about the details or harvest, you may discover it doesn't mix real well with free-range chickens
(tho a fence can certainly help, esp. if the chickens have plenty of other interesting places to rummage instead)
I am not anti-tractor, I have one myself (that's how I started) and use it and like it just fine, but especially for a flock of a dozen or so, and especially if you are concerned for lawn or aesthetics, I think a permanent coop probably on the balance has more going for it.
Have fun either way,
