Help please. I need to purchase either a clipper or shears for my sheep and angora goats, but I am confused about which to buy. They are not cheap, so I don't want to make a mistake. Basically, for the most part I need to be able to cleanup the sheep and goats for lambing kidding season, but also it would be nice if I could completely shear them sometimes. Can I use a clipper machine OR a shearer machine? what is the difference? Recommendations on brands/models/on line stores? Thanks.
