Hi, Carol
My book says that at weaning ewes can go on bare pasture or housed on straw. They will call for a couple fo days then settle, but can mother up again for up to three weeks after weaning.
Re. the udders - just leave well alone - if you milk them you will stimulate further milk production - which is obvious if you think about it. The milk, which should be minimal by now, given the age of the lambs, will be reabsorbed. You will need to look out for signs of mastitis in the ewes.
Hope this helps.
I'm so glad I'm following you in this!!
