DKS 2957: 2021 Foreword This Kenya Standard was prepared by the Animal Feeds Technical Committee under the guidance of the Standards Projects Committee, and it is in accordance with the procedures of the Kenya Bureau of Standards. It is expected that manufacturers will select their raw materials with both qualities of the product and economy of production in mind. The choice of raw materials mixtures will therefore vary according to the locality, season and availability of the ingredients. Proper formulation of diets for chicken depends on adequate knowledge of their nutrient requirements. This standard is intended to ensure that the diets of chicken contain adequate amounts of nutrients and that the intakes of certain nutrients are not excessive that they inhibit performance or impair health. During the preparation of this standard, reference was made to the following documents: Genetic and nutrition development of indigenous chicken in Africa- O Khobondo, T K Muasya, S Miyumo, T O Okeno, C B Wasike, R Mwakubambanya, A M Kingori and A K Kahi Commercial Poultry Nutrition: Steven Leeson and John D. Summers Third Edition (2005) Nutrient Requirements of Poultry: Ninth Revised Edition, 1994 The assistance received from these sources is acknowledged with thanks. iv KEBS 2021 — All rights reserved

Backyard Chicken Coop I made this little chicken barn a few years ago to house 3-5 laying hens in my back yard. I'm in town and had to design a "pretty" one to keep people from having a chicken coup (ha ha). This one was inspired by some Kansas barns I've seen. I spent about 40 when fully completed. Chicken wire, some 2x4s and damaged siding were

halves and garlic in chicken cavity. Tuck wings under chicken; tie drumsticks together. Place chicken over vegetables in slow cooker, breast side up. Mix rosemary, lemon juice, oil, paprika and remaining salt; rub over chicken. 2. Cook, covered, on low 6-8 hours. 3. Remove chicken to a serving platter; tent with foil. Let stand 15 minutes .
