These shearers are fairly expensive and require skill to operate. It is therefore easier for the small producer to hire someone to shear. If you still want to shear but cannot afford the electric shears, hand shearers are available. Vaccination and deworming is an important part of any flock's health program. Your local veterinarian can give you information on what is appropriate for your area.
Hoof care is one area often overlooked by the novice farmer.
Although many people trim hooves when they shear, I have found that sheep produce better with more regular hoof attention. I prefer to check feet monthly. Lame sheep are usually a result of poor feet. These sheep will not graze or feed properly. It can also be an indication of a more serious problem, such as foot rot.
