By daily attention to cleanliness, a few fowls may be kept in such a covered shed, without having any open run, by employing a thick layer of dry pulverised earth as a deodoriser, which is to be turned over with a rake every day, and replaced with fresh dry pulverised earth once a week. The dry earth entirely absorbs all odour. In a run of this kind, six square feet should be allowed to each fowl kept, for a smaller surface of the dry earth becomes moist and will then no longer deodorise the dung. Sifted ashes spread an inch deep over the floor of the whole shed will be a good substitute if the dry earth cannot be had. They should be raked over every other morning, and renewed at least every fortnight, or oftener if possible. The ground should be dug and turned over whenever it looks sodden, or gives out any offensive smell; and three or four times a year the polluted soil below the layer, that is, the earth to the depth of three or four inches, should be removed and replaced with fresh earth, gravel, chalk, or ashes.[2] The shed must be so contrived that the sun can shine upon the fowls during some part of the day, or they will not continue in health for any length of time, and it is almost impossible to rear healthy chickens without its light and warmth; and it will be a great improvement if part of the run is open. Another shed will be required if chickens are to be reared. Fowls that are kept in small spaces or under covered runs will require a different diet to those that are allowed to roam in fields and pick up insects, grass, &c., and must be provided with green food, animal food in place of insects, and be well supplied with mortar rubbish and gravel.
