Start heating the house and start the brooders 2 days prior to chick arrival to ensure that the house and equipment is warmed thoroughly. The 2 days of heating is often necessary because the equipment and litter will warm at a slower rate than the air (where temperature is measured). The water lines should be cleaned and disinfected at this time. Paper should be placed inside the cages adjacent to the feed trough or, in a floor system, on the floor under the feeders.
