Low humidity incubation was used for the fourth round on the Marsh RX incubator and the hatch was very good. During day 1 through 18 if the students were in class they added 1/4 cup of water to the incubator. Otherwise no water was added on non-school days or weekends.
On the 19th day a water tray with sponge was added for humidity during the hatch that took place on the 20th and 21st day.
Students are excited to take their chicks home today.
