Following hatch, birds decreased in
weight linearly, losing 0.14 to 0.17 g/hr in the
hatching trays ("able 2, Figure 1) for both
chicks and poults. Thus, chicks or poults held
for 48 hr in the hatchery decreased in weight
by 6 to 9 g, whereas birds hatching later and
close to removal from the trays exhibited
smaller decreases in BW.
