After hatching around day 21, the chicks have immediate access to feed and water. By contrast,
traditionally hatched chicks are in early life exposed to
dust and pathogens in the hatcher, handling procedures, and transport and remain without feed and water until they have arrived on the farm 1 to 3 D after
hatching. We compared welfare and performance of on farm hatched (OH) and traditionally hatched control (C) Ross 308 broiler chickens from day 0 to 40, housed
