I have mine on a track, I am not purist PP as I do think that horses should be able to graze a bit. My current track is in its infancy, I moved from my previous yard in June, that one had been in place about 4 years. I don't have very recent pics but have a few from this year, its still a work in progress as the field was left untouched for more than 10 years and the owner had run a skip business out of there prior to that and dumped all manner of stuff everywhere (there's a thread on the field progress somewhere).
Brown - permeant fences
Purple - outer electric fence
Red - inner electric fence
Yellow - part of inner electric but this is not fixed so moves up as I strip graze the middle
pink - hay stations (the very bottom one is inside the barn)
Black - areas the horses can't get to
Blue - water
My guys utilized the track at the old yard better (charged around it more), but I have had issues with the horse in the field on the right and my mare, they have spent the summer in love (Jess has given up now she's out of season but the gelding is still besotted) and so they camp out on that side a lot and for a while in the summer I had to block off that side as my squealing mare was putting her legs through the electric fence
, of course its the one open bit without trees or hedges to shelter them
Most of my hay stations are movable, I try to move them once a month so each area doesn't get too trashed, apart from the bottom right one, that's a post dug in to hang nets on.
Loafing area
They have access to the barn all the time
The field here was mostly weeds when I moved in so I had it sprayed in the summer which left a lot of it bare, so I am now mulching it with waste hay and barn sweepings to reseed it and rejuvenate the soil as we are very sandy here, I was also mowing it in the summer and mulching the cuttings on it. Hopefully in another 18 months I will have a much improved sward which will help it hold up to trampling hooves better and it will be more like the meadow I had at the old place. Although my yellow fence is my moving winter strip grazing one I do move the red and purple one too, but they can only move 6ft or so as I have those onto wooden in the ground corner posts to enable me to get good tension on the fence.
