This sketch shows an end view of a practical and inexpensive shed-roof laying house. Detailed blue prints for use in constructing such a house can usually be obtained from county agricultural agents or state agricultural colleges.] [Illustration: A fine flock of layers. The hoppers furnish laying mash and the fountains supply drinking water. Scratch grain is thrown in the litter.] The floor of the laying house must be dry at all times if vigor and health are to be maintained. During the winter there should be about 10 inches of dry litter in the form of straw, peat moss or shavings mixed with the straw. Small windows in the rear wall will make for better distribution of the litter, since the birds scratch away from the light. _Equipment and Appliances._--A great deal of hand labor and daily drudgery can be eliminated by equipping the house with properly constructed appliances. These will not only save labor but will also supply the birds with their needs at the time the need for certain materials is felt and thus contribute to health and flock efficiency. The best method of feeding dry mash is from a hopper. This should be so constructed as to hold a reserve supply at all times that will run into the feed trough as it is consumed. Care should be taken in construction to prevent the birds from throwing out the mash with their beaks and thus wasting it. Water fountains of a standard type that will furnish the birds with a constant amount of fresh water are available at poultry supply houses. Receptacles should also be provided for grit, ground oyster shell and charcoal which can be easily filled. A sloping board should be placed over these receptacles to prevent the birds from roosting on them and soiling the contents. Bins so constructed as to be vermin-proof and moisture-proof should be available for storing the scratch grain and other concentrated feeds. Provision for storing litter where it can be kept clean and dry will be necessary. If long straw is to be used, a cutter operated by hand or by a motor will prove useful in fining the straw. The scratch grain will be spread through the litter on the floor, compelling the birds to scratch for it and thus obtain needed exercise. _Artificial Lighting._--Modern laying houses are equipped with electric lights that are turned on and off automatically. Artificial lighting prolongs the hen's working day when the days are short, resulting in greater food consumption and more exercise which will increase egg production and give better health and stamina at seasons when more eggs augment profits. A 40-watt bulb should be placed in one receptacle with reflector for each 200 square feet of floor space, located midway between the front wall and the front line of perches.
