High altitude hatching advice

[kamac27]

I live at 10,000ft in Colorado and am hatching my first batch of chicken eggs sourced locally. Things inside the eggs were looking good at day 7 but at day 12 it looks like most embryos stopped growing. I’m using a nurture right 360 incubator running at about 100 degrees and 50-52% humidity. Started with 22 eggs, at day 7 19 were viable, then at day 12 only 2 look viable. I started reading about hatching being more difficult at higher altitudes but still confused as to the best temp and humidity levels for days 1-18 and then lockdown? Any advice would be greatly appreciated.

Hatching at high altitude

On my 3rd hatch now with a 360. Have not done well with either unit I own. I am ahving the same experience as you 2-4 duds. Others look viable. Most give up at between 5 and 10 days. I have had 3, 2, 2 hatch. Air cells never got very big even on the hatchers. We are at about 6500 FT in Sedalia. Next group I am going to try a dry hatch and not follow the instructions so closely. Also found that the temp is off on both by about 1/2 a degree high and the humidity sensor is off about 5% on the newer model I have and 7% on the older. Hope this helps.
