Great to hear someone else asking these questions - I've asked on various forums & received nothing much yet. I found a good website with examples, discussions, questions, etc; Paddock Paradise Questions, Answers ideas and solutions.
This has been very helpful & they are happy to email you. She is also interested in more examples for her website, particularly from people like us who need to compromise. My setup will be on there soon. Jaime Jackson is also apparently starting an official website on it, but that wasn't yet running last time I looked. I forget who said it, but someone said there wasn't much else as far as practical ideas in the book, so I haven't bothered to buy it yet.
I, along with so many others I've spoken to & know of, am in a similar situation to you Horsegma. Our 2 horses & pony live on a 100 acre mainly pasture property of which I pretty much have free rein - there are 6 other horses & nothing else on the property(cept roos, bunnies & wombats). We have a 3 acre & a 4 acre paddock fenced off for ours to rotate, and while they are all too fat, we can't afford the time or money to feed out f/t.
It's great for those who own the land & have good pasture, that they may be able to cut their own hay from the 'unused' centre of the 'paddock paradise', but the 'unimproved' pasture here isn't worth anything & I can't afford a hay contractor if I can't sell some to make my money back.
The other thing is, not being my own property, I can't afford & don't want to do permanent fencing, and have a limited budget for hotwire even, so this greatly limits my possibilities - otherwise I could just do a huge track around 50 acres or so, which would probably provide enough grazing.
So anyway, enough of the negatives, I'm a hoof care practitioner so I especially appreciate the benefits of this system for health & soundness. I'm determined to make it work for me! Hoping 3 of the other horses on the property might be joining ours too, as their owners are also interested. The more horses the better, movementwise. The more owners sharing cost of fencing the better, pocketwise!
My first effort has been one the shape of Hotreddun's paddock 3 diagram, around the outside of the 4 acre paddock. The dam is at the big end, gate & shelter is half way round and the narrow end is open, to allow them to graze the rest of the paddock. The majority of the track is 20' wide, as this was advised as about the maximum width that would still promote them to keep moving. They have to go thru the track to get a drink or shade, but go out to graze. I'm not sure whether they're getting all that much more exercise tho. We will be getting a load of crushed rock next week to put on one section for hoof conditioning, which will help.
Our next try is going to be an entire closed circuit, but with one end of the rectangle track being substantially wider - say 2/3 acre - for grazing. It shouldn't be too difficult to uproot the hotwire fence in order to rotate the section of grazing. If it runs out too quickly tho, we plan to open it up to the centre again, so they will only be locked on the track part time.
So anyway, I hope I've given you some ideas to try & hope you get lots more responses with more ideas for me too! Cheers.
