I don't know if these will help, but surprisingly, there are a number of videos of chicken coop building www.youtube.com/watch

i assume animals in captivity get dirty, so, make something you can service.

An old vehicle, say a van, with some wood shelving built-in, would function perfectly. ...
with the advantage of being largely pre-built , close to weatherproof, and movable as long as it had wheels under it. Just add nesting shelves plus rig sheltered entrances.

Such vehicles are advertised free or cheap in classifieds, Craigslist, community bulletin boards, word-of-mouth. You might just luck out and find somebody who wants nothing more than a legal place to dump their "worthless" old beater.

You are in Oregon? Build it where you can train a rifle on the entrance.
Fox, coyote, coy-dog, cat, skunk, you name it they may think that you laid out their lunch.

One suggestion I have for permanently sited coop is to build the run with cyclone fencing instead of chicken wire, and with a cyclone fencing "roof" as well. This way you can leave the chickens out when you go away for a day and they won't have to be "cooped up" so to speak. Also, every morning they can come out into the yard at dawn and don't have to wait for you to come and let them out. The only problem we had with this arrangement was when a bear actually dug a bear sized hole under the fence and ate a bunch of half grown chickens (feathers and all). Otherwise it's pretty bomb proof. People often want to get rid of cyclone fencing because they think it's ugly, so you are likely to be able to find it for free on craigslist or freecycle.

Also built a chicken tractor or portable coop last year out of almost all recycled materials for a family with a suburban back yard situation. The pictures of the finished coop got lost, but I'll post some pics to the tribe of the mostly finished coop before it had a roof. It turned out a little heavy to move very often, but otherwise was very cool. Some large wheels at the back would probably have made it easily portable, but they only wanted to be able to move it if necessary, not regularly. Light weight wood was used as much as possible, mostly old redwood. Here is a site with pictures of chicken tractors in case you decide to go that way. home.centurytel.net/thecityc...tors.html I'm building another one to use here, but it's on the back burner right now. A chicken tractor can also be an accessory to your chicken coop for when you want to control weeds, take advantage of some wild feed, and fertilize. Have fun! I miss my chickens.

Does any one have any ideas for a chicken tractor that can be easily moved and is appropriate for a slope? Please keep in mind that the slope varies so the base has to have some flexibility. I was thinking poly pipe...

I've built two coops where everything except three items were free or recycled. Nails, staples, and chicken wire I bought new, the shed to keep them dry in one case I made out of pallets with grungy plywood on top and ancient roofing shingles over it. In the second case I made the shelter out of 2x4's and some left over tin roofing for the top and sides. In both cases, I built an overhead framework tall enough to be able to walk around in of various kinds of wood (some 2x4 and various other left over lumber as well as downed limbs from the woods and stapled chicken wire too it. Pretty much have to have overhead cover to both keep hawks and owls out and to keep the chickens in. Plenty of room for them to run around, and once they are happy there ( a few months, you can let them outside and it won't be too hard to train them to come in at night by bringing them scraps or grain. (chickens -- guineas are another story).

hmmm, I think in fact I used some new hinges on one of the gates, though I do remember using some recycled hinges and latches on the other coop and gate into the aviary part. I don't know if it would be considered recycled or not, but at one point I had bought those 8'x10' dog run panels for 3 dog runs. The dogs were gone, and I used the panels as the walls for the aviary on the second coop.

Pallets are fairly easy to find, but forget about taking them apart, you pretty much need to use them as is due to the kinds of wood and nails used in building them. Some lumber yards and farm supply places often have a pile of discards and another pile of keepers.
