Visual inspection of the data showed that hatchery chickens, both male and female, weighed more than the control chickens for the duration of the study.

When comparing the male chickens, the hatchery chickens weighed significantly more on weeks: 1, 2, 3, 8, 9, 12, and 14 (p<0.05). There was also a tendency on week 10 for the hatchery males to weigh more than control chickens (p<0.1). There was no statistically significant difference in weight between hatchery and control chickens on weeks: 4, 5, 6, 7, 11, and 14 (p>0.1).

Comparison between female hatchery and control chickens showed that hatchery females weighed significantly more than control females on weeks: 1, 2, 3, 4, 5, 6, 8, 9, 12, and 14 (p<0.05). There were no statistically significant differences in weight between hatchery and control chickens on weeks: 7, 10, and 11 (p>0.1).
