Free choice hay and maybe a cup of Feed. Hard to say without more information. Are they pregnant, skinny, fat, do they have any available pasture or browse or it It a field of snow until spring thaw? What kind of hay do you have, what is available? Hair Sheep, wool breed?
Where was gonna be my question, too. Put some location in your profile, it makes a difference for replies most of the time. Weather plays a huge role in how/what many animals are fed and need....along with all the things Bay has asked.
