I see they are described as 'easy care', does this mean I don't have to do anything?

Wiltshire Horns are described as 'easy care' as their needs are incredibly low-maintenance relative to other sheep breeds.

They need to be vaccinated, drenched for worms (where worms are a problem) and they can get health problems like any other animal. However the labor (and problems) associated with wool is unnecessary - no shearing, crutching, certainly no mulesing, no dipping for blowfly or lice treatment. In terms of the husbandry needed, they are more like cattle or horses than Merinos.
