First try at it here last winter. I put a bale out every day and a strip of grass for 19 cows (was meant to be 20). Small paddocks and moving the water with them would be much better. Cows got fat could have done with another 10 there really will try again this winter with nearer 40.
Field has and is coming back well apart from one corner where it's a but damper and the tractor was driven through and one place where they were walking to water. Even the ring feeder scars are coming back as long as they were only used once. I'll try and get some pictures.
