2022 Reprint of the 1924 edition. Illustrated. Full facsimile of the original edition and not reproduced with Optical Recognition Software. This was originally published as Modern Fresh-Air Poultry Houses in 1924. Review: "To stay healthy, your chickens need plenty of ventilation-probably more than they're getting today. This was discovered over 100 years ago, but has been largely forgotten. Today's small-flock housing tends to be dank, dark, and smelly. Chickens, like miners' canaries, are easily harmed by poor air quality. Wet litter breeds disease. Darkness forces chickens, like parrots, to be artificially inactive. "Dank, dark, and smelly" is a deadly combination! Closed chicken houses are so harmful that knocking out a wall can cause an immediate improvement, even in winter. Chickens, after all, have a thick coat of feathers to keep them warm, but are vulnerable to poor air quality and pathogens in the litter; and their unwillingness to eat in the dark means they can starve in the midst of plenty." From a Review of the Norton Creek Press Edition: http://www.nortoncreekpress.com This title explains how to achieve this and provides ample illustrations and detailed instructions.
