Wow. Difficult to follow all that you are trying to accomplish.
What kind of chickens did you get? How big will they be? How many? That will determine basic size of a coop. In MA, if you aren't doing the coop part for the birds in the garage, you will need a large enough coop to keep them in during your snowstorms (doesn't all of MA get snow?).
Cattle panels are WONDERFUL things!! The page you showed from TSC had all kinds of livestock fencing. The reason hog, sheep and horse panels are more expensive than the cattle panel is simple. Smaller spaces between the squares = both more vertical and more horizontal pieces to be welded in. Material and time to build - even in mass quantities = higher $ amount. For our Shetland ponies and eventual goats - I'd love to have the 2"x2" horse panels - but at almost $60/panel (and at the TSCs here in NC it's $69/panel) - I can get 3 panels of the cattle (now a combo panel w/ smaller squares on the bottom - used to be all the same size and 52" tall rather than the 50" tall it is now) and cut it myself.
Don't know that you could bend an 8' panel around a kiddie pool or into a coop or run. Seems would be too short to me after I've used the 16' ones. BUT you could try. Cheaper to purchase the 16' ones and cut your own. Gardeners cut them all the time to use as trellis in combo with raised beds.
Our mature chickens can go right through a cattle panel by itself - whether it is in the regular setting or in an upright, curved hoop coop setting. Chicks can go thru that much faster. We didn't have problems with predators here (NC) on our previous property and not so far on our new set up either. SO - chicken wire works great - no HC on the sides OR as an "apron" on the ground. We covered our hoop coops completely with the chicken wire, then cover that with tarps to provide shade during the summer and cover during the rain, bit of snow and freezing precip we get. Eventually, our hoops will get covered with corrugated panels - think greenhouse type.
The link already shown has a fantastic set up by a fellow NCer. Made me drool! If you go thru the info on deep litter method, you'll see other hoop coops - BeeKissed has a great one and so does a woman in NY (I think). Also, Blooie (in WY or the Dakotas - wind, snow, cold) uses hers as a run with a connecting tunnel to their chicken coop. There are many others using the cattle panel hoop coops in different formats. Ours aren't fancy, but works for us. Still have some tweaking to do and things to build!
We currently have 3 different hoop coops - each made with a wooden base about 8'x10'. Each is slightly different in design, though not by much. To move them, though that was the original plan, is difficult! They are HEAVY - w/o added pop doors, hanging feeders, waterers, nesting boxes OR roosts. And ours don't have any wood sides/backs on them either. Also, we followed one design with the boards all the way around level and square. We have rough land and that makes it hard to pull them around - even if using a tractor, lawn mower or truck - both the front piece and the back piece "catch" on uneven areas, cacti (yep, got lots of that here on this new property), weeds, tufts of grass separate from other grass & brush. The "catching" is hard on whatever is used to pull it (think transmission/engine/clutch repair or painful shoulders/backs) AND also on the coop itself - each jolt works loose something somewhere.
Lots of pics to follow!
Building our first hoop coop -
After seeing several versions of a cattle/stock panel "hoop coop", I wanted one or several! So here is our first attempt - Juli and I are doing the build. It's already been a long day and this is turning out to be some work. Good work, but work. We get the panels zip tied together, then get them stapled to the 2x6x10 boards that will make the sides, then reverse it and stand it up. Then comes attaching the front and rear boards - hmmm... pre-drilling holes is wonderful!
Our granddaughters are checking it out! The bucket to the right side is the "pop" door. The end on the inside of the pen is cut out and to let chicken in/out, you just pull off the bucket lid (which can't be taken away as it's attached by a cord made from braided hay string). The front and back of this pen is 8' wide. The 2 cattle panels are 50" "tall" - so joined is 100". That's a little more than 8'. Say "coop" or "pen" is 8'x8'4". If it was made 3 panels long, it would be 8'x12-1/2'.
Who says you can't brood chicks in it?? These babies have been in the "coop" for a month already - these 3 were only 1.5 weeks old when I brought them home on October 17th. The first night, they spent in my feed room, then they were in a dog Xpen, covered in chicken wire, in this coop. They had the baby chick waterer and feeder, a "crate" they could bed down in w/ shavings, 3 sides blocked in so that heat could be retained and a warm light hanging from above. That whole thing is now out, they are eating/drinking w/ the two big girls (Australorps) but still have their light hanging. Will be putting in a baby roost for them this weekend near the light - they keep flying up to the buckets and feeder. The blue bucket ("pop" door) isn't open yet... No nest boxes yet here either - one of the next projects - soon - as the two black girls are about to start laying. We've started deep litter method with this coop - will be adding both leaves and pine straw again this weekend. Our property is predominantly sand - no way to remove it, so we are amending it thru the DLM.
pic is the other 2 coops. They will need to have more tarping done before winter hits here or I might have problems. But that will come - probably over Thanksgiving. They have since had quite a number of loads of pine straw and leaves added to them and need many more... They are sitting on top of hay/horse manure that happened when we didn't clean this section of the horse pen for 8 months. We shifted the horse pen, and put the hoop coops here. The bucket pop doors are now open and both the boys and the girls have learned to go out/roam and return at dark. Sometimes we find a boy in with the girls - I move them back... They are doing a GREAT job of aerating the horse manure NOT in their coops - YAAAYYYYY! Got 2" of rain today. They didn't drown and are quite happy.
The pen before "blue horse pen" moved over and chicken coops put on top of manure hay where Jazzy/Taff are standing in pic. You can see the blue horse pen in pic above - behind the coops.
That hay "rack" is a cattle panel wrapped around a round bale of hay. Jazzy has reached over (doesn't work so well w/ full size horses) and bent/folded up the panel. I removed these (had 2) and used these panels to hold the trash/bonfire burn pit instead.
We also have 2 sheds built from wood pallets and cattle panels (on our new property). The pallets are all the same size - 4'x4'. Then I hooped the panels for the ceiling/roofs. These aren't for the chickens right now, so no wire on them. But they'd work well for chickens. This was the first one we built when the ponies in temporary, leased quarters on 3 acres of land between where we moved from until we closed/moved into the new property. Worked great for 60+ days! Easy to put up and easy to take down and held up during snow, ice, rain and WIND. Cozy, too.
This is the first shed that we put together on the new property. It's about 10' wide x 8' deep. Reusing panels that have been moved/hauled long distances 2x means we now get some "funny" shapes... Right now it's connected by hay string. Plan on bolting it together eventually. Maybe before the pallets disintegrate...
This shed is 12' wide x 8' deep. It will be expanded this winter to 16' wide x 12' deep. It is also temporarily tied w/ haystring to hold it together. when we expand it, we will use bolts on the pallets and fencing staples on the panels to hold them in place. This area is much more level than the boys' area is.
And then we use them in the "traditional" way - for fencing in our ponies. Ponies are notoriously hard on this fencing - but it's so much easier to put up and also to replace if a pony "gets stupid"...
