So our situation set up is this - we have 21 acres total. When we moved in, there was one pasture fenced in short (too short but we will address that later) field fence. It's around approximately 7 acres (I think? - may be smaller). We built the pony paddocks, another pen behind the "barn" that was here, and the 60' round pen w/i that pasture. The paddocks are 30' off of the perimeter fence and the corners are angled so that large equipment can go around if needed/necessary. It also works as a "paddock paradise" track & driving/riding areas. AS of now, we don't have them all up yet - so I have a group of ponies running on the outside perimeter pasture. The boys paddock is along the side that is by the driveway & front gate. I have temporary feed sheds that will become permanent outside the boys pasture and one of the girls pastures. These sheds are built using 48" pallets for the sides and the cattle panels arched to form the roofs. The boy's feed shed is approx 8' x 10' and the girls' is currently 8' x 12' (getting ready to extend it to 12' x 16'). We have 1 arabian mare, 2 Xbred shetlands, & 29 purebred shetlands in this set up...
Well, this shot actually shows the mangled gate on the outside stud pen - closest to our driveway. Our Arab mare was being fed loose at the front of the pen. Larry, my hubby, rode his new bike (pedal, 10 speed type) along the drive way - outside the perimeter pasture - and she totally freaked out (guess we skipped that part of her training, oops). She ran backwards until she hit the end of the pen and then reared, flipping backwards over the panel (bending that section like a hammock). These are the ends that open in to the boy's pasture. The "feed shed" is outside the paddocks/pasture and is where I store feed, small # of hay bales and halters, leads, grooming equipment for the boys.
Another angle - I'm standing outside the boys pasture and have cropped this photo down. The front of the pens is to your right - also the front of the whole pasture. The bay/white in the "middle" of the shot is actually furthest away and is loose in his pen. The two silver pintos on either side of him are tied in the section that is between the two stud pens. The leaning gate hasn't been installed yet (cattle panel was shifted and doubled to install it for now). The larger bay pinto gelding is also tied in between the two stud pens - but is tied to the closer pen. There is a blue gate to the far left under that tree.
The section between the two stud pens. We can (& eventually will) make it into another pen. Right now, it's open and the boys come into it to be tied and fed at their buckets. There are 4 ponies in the pic below, the posts are set every 8'. You can see the gates at the ends of each paddock.
An angle showing the front of the pen closest to us above - with the feed shed outside the fence. The feed shed is approximately 10' wide? by 8' deep (2 48" pallets used for the sides, 1 pallet used for the back with an old door. I can put feed & hay out thru that open section. We have since put a different tarp on the roof and will soon be doing a different type roof (2 ltr plastic bottles over the two cattle panels).
The front of the boys pasture with the current geldings. They are standing about where there will be two gates installed. Right now the panels are angled to keep them up w/o posts and they are opened to allow my hay deliveries in 1x a month. The ponies are taken out via the smaller blue walk thru gates.
Our round pen is also built out of 16' panels and is currently housing the one stallion to keep him separate from the mares he was running with since the end of March. He will be gelded in September. The round pen is 60' diameter - the first time, ever, for us to have one this large. So far, it's only been used to house ponies, not as a working round pen, LOL...
We currently have the other two shetland stallions together in a large pen made from blue (economy) fence panels with a Shetland mare. This is not an arrangement I usually recommend, but for now, it is working for us. It probably wouldn't work at all if the 2013 colt hadn't been raised with the 2011 stallion since he was weaned. The older fellow is now chasing the younger fellow - but soon we will have the fencing finished (again) on the boys paddock and they will both go back out there - w/ more room to run/play/get away if necessary and no mare to fight over. The two boys are a bit thin here - had been running the other fence lines before brought into this pen. In the 3 weeks since, they've put their weight back on.
