Why are most chickens raised indoors in Canada? Ask us this question in Thunder Bay in the middle of a snowstorm in January! Kidding aside, barns are designed to provide the birds with the right environment, protected from extreme weather and temperatures, and of course the age-old problem of predators like wolves and coyotes.
In modern chicken barns, like these two that were built in 2006, the temperature, humidity, light and ventilation are all carefully monitored. These barns help keep the birds cool in the summer and warm in the winter. They have fans to help circulate the air. This barn also has a water misting system that helps to keep the birds comfortable in hot weather (think of running through the sprinkler, when you were a kid, on a hot summer's day). Another reason for indoor housing is for animal monitoring and care. It's much easier to ensure each bird gets the right food, clean water and care in a barn than when they are outside.
