Chicken Farm Sites Chicken farms have large numbers of chickens. With this large number of birds in one area, a large amount of chicken manure is produced. Chicken manure is collected and stored for use as fertilizer on crop land. Since the manure is often stored for long periods of time, farmers only empty the manure storage a few times a year. When a farmer is cleaning the storage area and spreading the manure, odors can be very strong.
Many factors determine the range and strength of odors.
These include humidity, temperature, distance from the farm, topography, and wind direction. Many of these a farmer has no control over. Chickens can sometimes be noisy animals. If you live near a chicken farm, you might hear chickens making noises at all hours the day and night. Layer and broiler houses have few windows, especially where the birds are kept.
