:wave:Whereabouts are you?
Highlands are certainly low maintenance. Because they can survive on poor grazing, their digestive system is 30% more efficient than that of the "improved" breeds.
They require no housing in winter. In fact they do not like being totally enclosed, although they will use an open building for shelter, so long as they can come and go at will.
So they don't need concentrates or any extra feeding, but will happily overwinter on hay alone and produce a decent calf and sufficient milk for it.
