Days 20 going into days 21 and No hatch

[djben]

I put my coturnix quail eggs in my incubator at 6pm on April 28 and now it's May 19 and no sign of hatching. What did I do wrong? I have a force air with auto turner. My temp are around 37.5 C to 37.8 C range. my Hum. are around 50-55 through out the incubation period and into lock down. These are my own eggs and the Infertile eggs are being toss before lock down. How long should I wait? what could impacts the eggs? I'm new to this and this is actually my first batch. Any quail people...help! Thanks!

Humidity should be 45 ... this can affect the hatch adversely

Yallapilko is right, too high humidity. Qual eggs need to loose some weight before lockdown and high humidity doesn't help there. Also when going into a lockdown humidity should be 70-75%, this helps to soften the eggshell and membrane to help chicks hatch. Do a water floating test (youtube has a lot of great videos, make sure eggs have no cracks in them) to find out if the eggs are still viable. If they are, increase humidity to 75% and pray/wait for them to hatch.
