male Arbor Acre Cross chicks were obtained
from a local producer, banded
and
distributed randomly
into
groups,
and
placed into pens positioned in
electrically
heated batteries with
raised
wire floors. Birds were housed
in
a windowless room at 73.4ºF and
14
hours
of light per day. Feed and water
were administered on demand.
