talking about those posts at all.
What I mean (and what, from your additional description, sounds to me like the ONLY safe and structurally-sound option I can think of) is to buy the pre-made chainlink run
. Assuming the coop wall will be one wall of the run, you will need 3 panels -- they're generally 6' high, and mine are 12' long but I believe you can find other lengths too. You know the ones I mean? They are like already framed out in metal pipe, so each panel is a rigid structure in and of itself. Get 3, attach them at 2 corners and to the coop wall, and put in t-posts at the corners to affix them to the ground.
Dog runs are out of the question as well, you just cannot find them used for cheap here, it's not possible, people hang onto them.. and buying one from
TSC is landing you $200-up a panel!
Chick-a-dee, I know we've been through this before so I will try to be brief, but I just have to remind you ...
I live only a little over two hours away from you (realio trulio. I timed it last time I drove past Kingston. *Four* hours gets me well into NY State, around Watertown). It is really
not so difficult to find used kennel panels for sale in Ontario. (Not what I'd consider difficult, anyhow). Yes, you have to look around for a while, but I see them advertised fairly frequently, and at farm-type auctions, in various places between Barrie and the Kawarthas and Cobourg. I realize that only the eastern part of this area is relevant to you, but this area is not likely to be unique.
Sure, it may well be that there are fewer out your way, but it would only cost sixty or eighty bucks to rent/gas a truck and go pick panels up from somewhere else. Sheesh, even if you bought the panels full-retail brand spankin' new from
TSC or Home Depot or wherever, that's still not THAT expensive for a run-- remember, you would have to buy NOTHING else besides two measly t-posts ($4 each at farm auction, or free if you have some unused ones on the property). Whereas, otherwise you have to buy a buncha wire mesh, plus something to stiffen the top at *least*.
The thing is:
Farmers use t-posts to keep their cattle in, and they use a high tensile paige wire fencing... why wouldn't that keep chickens in?
Sorry, chick-a-dee, they DO NOT string high tensile fence on t-posts. No way! LOL
T-posts are often used as some of the l
ine posts for that kind of fence, but that's absolutely NOT what is holding the fence up. Next time you are driving around, take a closer look. The corners are HEAVY cedar posts, well-braced diagonally against adjacent cedar posts, and usually every 2nd or 3rd line post is a cedar post too. (the ones that don't have some wooden line posts are the ones you generally can't see very well b/c they've fallen over and disappeared into the long grass... NOT a coincidence
)
T-posts just have relatively little resistance to tipping over, no matter how deep you drive them. This makes them suck badly as corner posts (even just for electric rope horse fences, although you can get away with 'em that way as long as you don't mind them very very slowly keeling over). With anything that imposes more stress on the corner -- like a long, or tight, or high-wind-resistance fence -- they will just go right over within weeks or months. Requiring you to rip the entire darn thing out of the ground, which is TOUGH, and re-do it.
Attaching the tops together all along the run will provide a *little* extra stability, but not frankly all that much. And remember, your run fence a) catches a lot of wind, and b) has to be STRONG so that when coyotes stand up against it, or raccoons climb over it, it does not sag over and stay there. (I know your chickens will be in at night, but it will be very annoying to have predators damage the run fence so that you have to rebuild it. Best to do it right the first time).
I thought of another alternative for you, btw. If you do not want to spend the money upfront on kennel panels, BUILD YOUR OWN. I'd use the heaviest lumber that's feasible -- at least 2x6's for the horizontal members, and 4x4's for the corners and probably for one 'line post' per panel as well. Personally I'd use p.t. for most if not all of it. Bolt them together securely into a 5-6' by 10' frame (make 3 of these). If you use 1 or 2" welded wire mesh you could probably get by without diagonal braces; otherwise, brace diagonally. Then staple or screw some strong wire mesh on -- personally I would not use anything bigger than 2x4" mesh. You *could* use chainlink, if you have a 'free' source, but it will be disproportionately annoying to work with and get installed properly and I really wouldn't bother. Then affix the panels together into a run, using t-posts at the corners to make it keep its shape and to encourage it to stay attached to the ground.
Or, don't, it's a free country. I'm
trying to help you out, though.
Good luck,
Pat
