One of the hardest problems in successful poultry keeping is to maintain the vigor and health of the flock. Housing has particular bearing on this problem. If the laying-house is poorly lighted, has insufficient ventilation, or is overcrowded, the health of the fowls will be affected. The purpose of housing is to increase productiveness. In order to accomplish this the fowls must be comfortable.
“Yes, with this approach to farming we make decisions and put our hands to some small manipulations but the very breadth of mixed crop and livestock systems often quickly leave us behind and spread out to do their own work of symbiotic osmosis and complementary relations.”
Mayfield Farm is a small family owned and operated mixed farm situated at 1150 m above sea level on the eastern edge of the Great Dividing Range in northern New South Wales, Australia. Siblings, Sandra and Ian Bannerman, purchased the 350 acre property in October, 2013, and have converted it from a conventionally operated farm to one that is run on organic principles. Additional workers on the farm include Janette, Ian’s wife, and Jessica, Ian’s daughter.
Outside my kitchen window, falling leaves gather over the crude nest claimed by a chicken last June. I can no longer see the soft white under-feathers she left behind. I imagine this wouldn’t have seemed at all remarkable to the woman who stood here, at the sink, in the 1930s when this simple home was the heart of the Central Egg Company in Petaluma, California. A rusted remnant of that sign still clings to the main warehouse building. The last of the chicken houses dropped to its knees long ago.
The importance of poultry-house ventilation is generally conceded, but just what is meant by ventilation and how it may be accomplished is not so well known. It is becoming increasingly evident that adequate ventilation cannot be accomplished merely by throwing doors and windows wide open to let the wind blow into the house; the air conditions within the pen must be so controlled that weather has only a secondary effect.
