My lleyns were on 600-750g 18% nuts a day. I had one that was in for 3 weeks post lambing as I had nothing to turn her out with and the lambs really have been pulling her down. All turned out this week- be brave, see a break in the weather and put them out, the ewes will milk better and less disease risk. Ours went out this week, lambs between 2-5 days old all with lamb macs on but all doing well and the ewes are brimming with milk now they are on grass. Yes it’s wet out there but providing there’s a big of grass they will be better out
