Chicks not hatching

[calasu]

What am I doing wrong? I get fully formed chicks and then take them out of the turner and put them in the incubator to hatch and then a few hatch but there are fully formed chicks with yolks that die rather than hatching. I have my humidity around 70%.

Check your humidity gauge and make sure it's not reading way off. Do any pip and die? That could be either to high humidity (they drown) or too low (sticky chicks).

Also check your temps, by day 21 the really shouldnt have yolk left. There is wonderful information on this forum, read it all.
