Show Well-Ventilated House Needful During Winter A warm poultry house that will help to keep egg production high during the winter months must be well ventilated, venti-lated, says Prof. E. R. Gross,' agricul. j tural engineer at the New Jersey ex-: ex-: periment station, New Brunswick. To maintain a warm, well-ventilated henhouse three things are needed, advises ad-vises Professor Gross: Tight walls, doors, and windows; ventilating flues, which may be constructed of wood at a low cost, and limited overhead space. To make the building tight, close all the cracks, cover the outside walls with roll roofing, or ceil the inside walls. Reduce the air space by ceiling ceil-ing overhead or by constructing a straw loft. Ventilation and warmth go together. If the house is tightly built and has all doors and windows closed, the birds will give off heat enough to raise the Inside temperature considerably above that on the outside. But when the house Is tightly closed, moisture will begin to accumulate and the air become stale. Ventilation Is needed, therefore, to carry away the moisture and to bring In fresh air. |
