POULTRY A chicken tractor for your garden A chicken tractor is a mobile chicken coop, wholly or partially without a floor, which lets From page 37 K Sheep & Goats When you are measuring the girth of a sheep, ensure an accurate measurement by compressing the sheep's wool so that the circumference reflects that of the body and does not include that of the body plus the wool. Body length refers to the distance your poultry forage freely on the land, while protecting them from the elements and predators. from the base of the ear to the base of the tail (where it joins the body). For goats, the length of the animal from the point of the shoulder to the pinbone is measured. The tape must be pliable enough to bend around to the point of the shoulder and to the pinbone. For sheep and goats calculate body weight using Schaeffer's formula for the weight in pounds, which can then be converted to kilograms, ie heart girth x heart girth x body length/300 = animal weight in pounds. Divide the result by 2,2 to get the weight in kilograms. For example, if a sheep has a The thinking behind it is that the chickens then do a wonderful job of clearing a patch of weeds, weed seeds, insects and grass, as well as loosening the soil and spreading their manure the heart girth equal to 35 inches and a body length equal to 30 inches, the calculation would be (35 x 35 x 30)/300 = 122 lbs. Divide by 2.2 = 55.45 kg. Alternatively, use the Minnesota formula for the result in kilograms directly. Continued on page 41 ANIMAL HUSBANDRY 39 www.sasmallholder.co.za
