Chicken farmers, like William, thoroughly clean their barns out after each flock of chickens leaves and before the new flock arrives. Disinfection of the barn is an important part of William's on-farm food safety program. All the manure is removed from the barn. Walls, ceilings, floors and all equipment is cleaned and disinfected.
A few days before the day-old chicks are scheduled to arrive, William will cover the barn floor in fresh wood shavings for bedding using the machine shown in this photo. He'll lower the feed and water lines to the right height for the new birds and he'll begin increasing the temperature in the barn to 33 degrees so that it's ready for the new chicks.
