Broilers from eggs incubated in different incubator tray locations all received a common corn and soybean meal–based diet provided in 3 phases: starter (day 1–13), grower (day 14–33), and finisher (day 34–41). Pen served as the experimental unit with 20 replicate pens (12 birds per pen) per treatment.
