Janoel8-48 Conitnues Low Percentage Hatch

Hatch number eight with Janoel8-48 resulted in a 37.5% hatch and I was disappointed in these results.  I followed the dry humidity incubation method; day 1 through 18 I didn't add any water to the incubator.  The incubator humidity measured 12-15% most of the time and when a storm passed through the humidity raised to 21%.  Day 10 candling was promising with only a handful of clears.

Day 19 the eggs were removed from the egg turner and I added 2 cups of water to the water channel.  This raised the humidity to 60-65% and it remained at this reading through the end of day 21.  Most of the chicks hatched on day 20.

At the end of day 21, I opened the lid and removed the chicks.  I had 2 eggs cracked open, but the chicks were stuck to their membrane and they were all slimy for being in the egg too long.  The water channel was completely dry and I was bother with viewing a dry water channel and the humidity reading was still showing 60% at the end of day 21.  The incubator needed a little water for those last chicks to hatch properly.

Over a dozen eggs didn't hatch and after inspection 6-8 of those eggs were fully developed and something failed towards the last stage for a hatch.  Not sure if the 2 cups of water was too much and the eggs absorbed the water, causing a drown when the chicks peeped the air sac or something else is going on and I haven't figured this problem out yet.

On the next incubation I will only add 1/4 cup of water at day 19 for humidity rate of 45% and add 1/4 cup daily through day 21 and analyze the results.

On a brighter note I have sitting hens who are hatching eggs without issues.

Productive Marsh RX Automatic Fourth Round Hatch

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.
