I like the suggestions coming out of this
thread.
Your traditional coop and run idea can be used, if large enough, and divvied up with electronet fencing as Redhawk suggests. You could have a more free-form run area, if this works for you, enriching more of the area around the coop,
should you need to keep it in one place.
Personally, if I had an acre for chickens, I would do it with a mobile coop, albeit a large one. I like the idea of designing it for storage of the electronet fencing and whatever infrastructure it requires, such that all I have to do in the morning is move the coop and park it, and then drop the posts around the coop.
I think there are several techniques available to provide healthier supplemental
feed to your chickens than just commercial feed, even in the winter, when you may get nothing. Fermenting grains in buckets or growing sprouts on trays comes to mind, and there's always your own food scraps. You can even include insect production in the mix, should your waste stream warrant it.
In winter, I have often seen hoop row covers suggested for sheltered outside access, usually on otherwise bare-dirt areas. Winter feed could be thrown in there, and instead of creating a dead-zone area some colloquially call a sacrificial paddock, their manure enriches next season's
garden bed. The mobile coop could be situated on one end of the tunnel, connected to it.
Incidentally, you could take styling cues from the tiny house movement to make your mobile coop aesthetically pleasing. If you really like the way your house looks, you could mimic its architectural style down to colour and trim. You could just work in the same colour palette, or you could choose a contrasting design aesthetic that you think works well in the space.
There's nothing saying you can't have an attractive mobile coop you can brag about. Keep in mind that in many cases, because you're building something relatively small, you can reclaim the best bits of a tear-down
project (lets say someone in your neighbourhood is re-roofing their slate, cedar shingle, or clay tile roof) and put them to your use. That way, your coop can genuinely reflect the character of the area.
In any case, keep us posted as to what you do, and let us see pictures, if you don't mind. Keep it up, and good luck.
