Nah - the 'easycare' component refers to the management system and the ewe itself. 'Easycare' management systems are usually all grass based, outdoor lambing systems with culling/selecting for desirable traits. 'Easycare' ewes are those which have been selected for traits that make them easy to manage (although they are also a breed of sheep created with this in mind, and those are what is for sale on that website). The usual traits are: wool shedding (no shearing, dagging, much reduced flystrike, minimal spending on strike treatments) ease of lambing, culling for feet (and I have heard that this is where the easycare breed were faltering), an a bility to fatten lambs off grass and some breeders are now breeding for worm resistance too.
