Hi lomine-
I've been playing around with hatching at altitude for about a year now. It's like Christmas, only more frustrating and you don't get what was on your list. My hatch rate runs around 50% on a good day, 0% on a bad. Having said this, my incubator hatches are not "typical". Right now, I am using a brinsea 20 with a humidity pump. Paid out the big bucks, because my typical house humidity is like 15%. I knew that controlling the humidity would play a large part of figuring out the rest of my issues. Have tried "dry hatches" with no luck at all. Right now, I run the incubator at 45-50% humidity until lockdown and then bump to 68-72%. I do serial runs and add 4-5 eggs every week, because I was trying to target a mating pair. At first I removed the other batch to another (inferior) incubator, but now am trying to just hand turn the non-lockdown eggs. Still have 2 batches to go with this method. The first batch of 4 eggs did not hatch, but discovered I had closed the air intake hole, duh! We'll see what happens next! B1 had 2/4 hatch, B2 1/4, B3 0/4 B4 due this wed.
Experimented with soda lime too, but halting all the variables for a while. May go back to it again. By the way, I'm at 7800'.
This is what a quail Belgian d'Anver looks like when you get it right!
