Balancing air/litter quality with propane usage during cold weather has always a been challenge for poultry producers. But now, with the price of propane climbing to over two dollars a gallon, what before was a challenge, for many now seems to be nearly impossible. Attic inlets are looked upon by many as a possible partial solution to this dilemma. Though attic inlets do have the potential to decrease the cost of heating a poultry house, their most significant impact has been that by pulling 5oF... to 30oF warmer air out of the attic during the day, poultry producers are able to ventilate their houses 20% to 100% more without increasing heating costs. The higher daytime ventilation rates have significantly improved both house air and litter quality.
